    This study examined the effects of treadmill running (TR) regimens on craniofacial pain- and anxiety-like behaviors, as well as their effects on neural changes in specific brain regions of male mice subjected to repeated social defeat stress (SDS) for 10 days. Behavioral and immunohistochemical experiments were conducted to evaluate the impact of TR regimens on SDS-related those behaviors, as well as epigenetic and neural activity markers in the anterior cingulate cortex (ACC), insular cortex (IC), rostral ventromedial medulla (RVM), and cervical spinal dorsal horn (C2). Behavioral responses were quantified using multiple tests, while immunohistochemistry measured histone H3 acetylation, histone deacetylases (HDAC1, HDAC2), and neural activity markers (FosB and phosphorylated cAMP response element-binding protein (pCREB). The effects of both short-term TR (2 days, TR2) and long-term TR (10 days, TR10) regimens were conducted. TR10 significantly reduced anxiety- and formalin-evoked craniofacial pain-like behaviors in SDS mice. It normalized SDS-induced increases in histone H3 acetylation in both the anterior and posterior portions of the ACC, as well as the anterior portion of the IC. These inhibitory effects were also observed in SDS-related increases in HDAC1, FosB, and pCREB expression. Additionally, TR10 normalized increased histone H3 acetylation in the RVM and C2 regions, with specific effects on FosB and pCREB expression observed in the C2 region. In contrast, TR2 showed limited effects on craniofacial pain-like behaviors but reduced anxiety-like behaviors in SDS mice. Under sham conditions, TR2 had minimal impact on histone H3 acetylation. Paradoxically, TR2 increased formalin-evoked craniofacial pain-like behaviors during the early phase despite not altering acetylated histone H3 expression. In conclusion, the TR10 regimen is effective in attenuating SDS-induced craniofacial pain- and anxiety-like behaviors, likely by normalizing epigenetic modifications and neural activity in key brain regions.

    This narrative review provides an overview of current knowledge on the impact of nutritional strategies on chronic craniofacial pain associated with temporomandibular disorders (TMDs). Individuals experiencing painful TMDs alter their dietary habits, avoiding certain foods, possibly due to chewing difficulties, which might lead to nutrient deficiencies. Our literature investigation revealed that the causal links between nutritional changes and craniofacial pain remain unclear. However, clinical and preclinical studies suggest that nutraceuticals, including vitamins, minerals, polyphenols, omega-3 fatty acids, isoprenoids, carotenoids, lectins, polysaccharides, glucosamines, and palmitoylethanolamides, could have beneficial effects on managing TMDs. This is described in 12 clinical and 38 preclinical articles since 2000. Clinical articles discussed the roles of vitamins, minerals, glucosamine, and palmitoylethanolamides. The other nutraceuticals were assessed solely in preclinical studies, using TMD models, mostly craniofacial inflammatory rodents, with 36 of the 38 articles published since 2013. Our investigation indicates that current evidence is insufficient to assess the efficacy of these nutraceuticals. However, the existing data suggest potential for therapeutic intervention in TMDs. Further support from longitudinal and randomized controlled studies and well-designed preclinical investigations is necessary to evaluate the efficacy of each nutraceutical intervention and understand their underlying mechanisms in TMDs.

    Mutations in Dystonin ( DST ), which encodes cytoskeletal linker proteins, cause hereditary sensory and autonomic neuropathy 6 (HSAN-VI) in humans and the dystonia musculorum ( dt ) phenotype in mice; however, the neuronal circuit underlying the HSAN-VI and dt phenotype is unresolved. dt mice exhibit dystonic movements accompanied by the simultaneous contraction of agonist and antagonist muscles and postnatal lethality. Here, we identified the sensory-motor circuit as a major causative neural circuit using a gene trap system that enables neural circuit-selective inactivation and restoration of Dst by Cre-mediated recombination. Sensory neuron–selective Dst deletion led to motor impairment, degeneration of proprioceptive sensory neurons, and disruption of the sensory-motor circuit. Restoration of Dst expression in sensory neurons using Cre driver mice or a single postnatal injection of Cre-expressing adeno-associated virus ameliorated sensory degeneration and improved abnormal movements. These findings demonstrate that the sensory-motor circuit is involved in the movement disorders in dt mice and that the sensory circuit is a therapeutic target for HSAN-VI.

    This study determined the effect of daily administration of Rice-koji on anxiety and nociception in mice subjected to repeated forced swim stress (FST). In a parallel experiment, it was determined whether ergothioneine (EGT) contained in Rice-koji displayed similar effects. Anxiety and nociception were assessed behaviorally using multiple procedures. c-Fos and FosB immunoreactivities were quantified to assess the effect of both treatments on neural responses in the paraventricular nucleus of the hypothalamus (PVN), nucleus raphe magnus (NRM), and lumbar spinal dorsal horn (DH). FST increased anxiety- and pain-like behaviors in the hindpaw. Rice-koji or EGT significantly prevented these behaviors after FST. In the absence of formalin, both treatments prevented decreased FosB expressions in the PVN after FST, while no effect was seen in the NRM and DH. In the presence of formalin, both treatments prevented changes in c-Fos and FosB expressions in all areas in FST mice. Further, in vitro experiments using SH-SY5Y cells were conducted. Rice-koji and EGT did not affect cell viability but changed the level of brain-derived neurotrophic factor. In conclusion, Rice-koji could reduce anxiety and pain associated with psychophysical stress, possibly mediated by the modulatory effects of EGT on neural functions in the brain.

    The conditions of stress contagion are induced in bystanders without direct experiences of stressful events. This study determined the effects of stress contagion on masseter muscle nociception in mice. Stress contagion was developed in the bystanders after cohabitating with a conspecific mouse subjected to social defeat stress for 10 days. On Day 11, stress contagion increased anxiety- and orofacial inflammatory pain-like behaviors. The c-Fos and FosB immunoreactivities evoked by masseter muscle stimulation were increased in the upper cervical spinal cord, while c-Fos expressions were increased in the rostral ventromedial medulla, including the lateral paragigantocellular reticular nucleus and nucleus raphe magnus in stress contagion mice. The level of serotonin in the rostral ventromedial medulla was increased under stress contagion, while the number of serotonin positive cells was increased in the lateral paragigantocellular reticular nucleus. Stress contagion increased c-Fos and FosB expressions in the anterior cingulate cortex and insular cortex, both of which were positively correlated with orofacial inflammatory pain-like behaviors. The level of brain-derived neurotrophic factor was increased in the insular cortex under stress contagion. These results indicate that stress contagion can cause neural changes in the brain, resulting in increased masseter muscle nociception, as seen in social defeat stress mice.

    We investigated the effects of social defeat stress (SDS) and treadmill running on masseter muscle nociception, which was quantified by the orofacial formalin test and c-Fos and FosB immunoreactivities in the upper cervical spinal cord (C1/C2) region in male mice. After daily SDS or non-SDS conditioning for 10 days, SDS-conditioned mice were categorized into SDS-susceptible versus resilient mice. Several mice, including non-SDS-conditioned, SDS-susceptible, and resilient mice, were selected to assess masseter muscle nociception on Day 11. SDS conditioning for 10 days increased masseter muscle-evoked nocifensive behaviors and c-Fos and FosB expression in SDS-susceptible compared to non-SDS and resilient mice. The remaining SDS-susceptible and non-SDS mice were subjected to an additional 10 days of SDS plus treadmill running or sedentary sessions before assessing masseter muscle nociception on Day 21. Daily treadmill running sessions reduced enhanced masseter muscle nociception in SDS-susceptible mice but not in non-SDS mice. The preventive effects of daily treadmill running immediately after each SDS conditioning for 10 days on orofacial nocifensive behaviors were assessed on Day 11. Treadmill running conducted immediately after daily SDS inhibited enhanced orofacial nocifensive behaviors. These findings indicate that repeated SDS increases masseter muscle nociception, which could be prevented by daily treadmill running exercise.

    This study was designed to investigate the effects of Sake Lees extracts (SLE, Sake Kasu) on the functional activity of odontoblastic cells and tooth pulp of the rats. For in vitro studies, a rat clonal odontoblast-like cell line, KN-3 cells were cultured. SLE significantly decreased KN-3 cell proliferation, but showed no significant cytotoxicity. SLE effects on several protein productions of KN-3 cells were compared with PBS. SLE and PBS increased alkaline phosphatase (ALP), dentin sialoprotein (DSP), and osterix in a day-course dependent manner, while SLE increased the induction of ALP on day 9-21 and DSP on day 15-21. SLE also increased Runx2 expression on day 3 and 9 compared to PBS. Alizarin Red stainings revealed that SLE showed a subtle increase in mineralization of KN-3 cells on day 15 and 21. A histological investigation was conducted to assess if SLE induced reparative dentin formation after direct capping at the exposed tooth pulp in rats, suggesting that SLE could increase the reparative dentin formation more than PBS. These findings suggest that Sake Lees could have functional roles in the alterations of odontoblastic activity, which might influence the physiology of the tooth pulp.

    Dystonin (Dst) is a causative gene for Dystonia musculorum (dt) mice, which is an inherited disorder exhibiting dystonia-like movement and ataxia with sensory degeneration. Dst is expressed in a variety of tissues, including the central nervous system and the peripheral nervous system (PNS), muscles, and skin. However, the Dst-expressing cell type(s) for dt phenotypes have not been well characterized. To address the questions whether the disruption of Dst in Schwann cells induces movement disorders and how much impact does it have on dt phenotypes, we generated Dst conditional knockout (cKO) mice using P0-Cre transgenic mice and Dst gene trap mice. First, we assessed the P0-Cre transgene-dependent Cre recombination using tdTomato reporter mice and then confirmed the preferential tdTomato expression in Schwann cells. In the Dst cKO mice, Dst mRNA expression was significantly decreased in Schwann cells, but it was intact in most of the sensory neurons in the dorsal root ganglion. Next, we analyzed the phenotype of Dst cKO mice. They exhibited a normal motor phenotype during juvenile periods, and thereafter, started exhibiting an ataxia. Behavioral tests and electrophysiological analyses demonstrated impaired motor abilities and slowed motor nerve conduction velocity in Dst cKO mice, but these mice did not manifest dystonic movements. Electron microscopic observation of the PNS of Dst cKO mice revealed significant numbers of hypomyelinated axons and numerous infiltrating macrophages engulfing myelin debris. These results indicate that Dst is important for normal PNS myelin organization and Dst disruption in Schwann cells induces late-onset neuropathy and sensory ataxia. MAIN POINTS: Dystonin (Dst) disruption in Schwann cells results in late-onset neuropathy and sensory ataxia. Dst in Schwann cells is important for normal myelin organization in the peripheral nervous system.

    Psychophysical stress can cause neural changes that increase nociception in the orofacial region, particularly the masseter muscle (MM). The nucleus raphe magnus (NRM), which is located in the brain stem, serves the crucial role of regulating nociception through descending modulatory pain control. However, it remains unclear if neural activities in the NRM are affected under psychophysical stress conditions. This study conducted experiments to assess (1) whether neural activity, indicated by Fos expression in an NRM that has experienced MM injury, is affected by the stress of repeated forced swim tests (FST); and (2) whether the selective serotonin reuptake inhibitor fluoxetine administered daily after an FST could affect the number of Fos-positive neurons in the NRM. Results revealed that the stress from repeated FSTs significantly increased the number of Fos-positive neurons in an NRM that had been affected by MM injury. Fluoxetine inhibited increases in the number of Fos-positive neurons in the NRM that occurred as a result of FSTs, but this was not observed in sham rats. These findings indicate that the stress from FSTs could increase nociceptive neural activity in an NRM that has experienced MM injury. This could be due, in part, to changes in serotonergic mechanisms.

    新潟大学歯学部では,初年次教育として大学学習法を実施している.この授業は講義・演習での知識や技能をもとに,レポート作成とプレゼンテーションを行うもので,その学習活動を通して,間題解決能力,論理的思考力,表現力の開発をねらいとしている.今回,学習成果の直接評価に向けて,パフォーマンス評価を導入すべく,レポートからこれら能力を読み解くルーブリックづくりに取り組んだ.また,この経験からみえてきたパフォーマンス評価の難点とその対処について検討した.その結果,パフォーマンス評価により能力を把握できる可能性が示されたが,導入には教員の理解と協力,能力と関連した適切な評価観点の設定,評価の信頼性を高める工夫,評価と指導の一体化を考慮した授業デザインなど,いくつかの課題があることも明らかになった.The curriculum of Niigata University Faculty of Dentistry provides the &quot;Study Skills&quot; course as first year education. The ultimate goal of this course is to develop student abilities of problem solving, logical thinking and expression. For that purpose, each student is guided through the process of writing a report and presenting its content. To access the degree to which these abilities were achieved, we created a rubric and used it to evaluate the student reports. Based on the experience of this trial, we discussed problems for the introduction of performance assessment into the course. Although performance assessment has a high potential to grasp these abilities, there are some practical problems that may interfere with its introduction, such as &quot;how to involve the faculty in assessment&quot;, &quot;how to establish dimensions of the rubric that appropriately relate with the student abilities&quot;, &quot;how to increase the reliability of assessment&quot;, &quot;how to design the course to allow for a connection between assessment and instruction&quot;.

    高齢者社会に突入した現在の日本において、食事を口腔から摂取することが困難な患者が増加していることが、しばしば医療および介護の現場で問題になっている。我々の研究室では、摂食・嚥下障害の問題を解決するための応用研究に取り組んでいる。これまでの嚥下誘発に関する動物実験を詳細に検討し、ヒト経鼻的電極を考案した。ヒトの咽頭領域へ電気刺激を与えることにより、再現性のある嚥下誘発方法を開発した。さらに、実際の食事行動を想定し、ヒト嚥下誘発システムによる電気刺激と同時に咽頭・喉頭領域へ味刺激を与え、味覚刺激の嚥下誘発に対する効果を検討している。

    近年の我が国の社会経済構造等の変化に伴い「食」に関する様々な問題が顕在化しているが, 歯学的な観点からこれらの問題を考えると, 内含している問題点がライフステージにより異なる. 高齢者においては平均寿命の延伸に伴い咀嚼・嚥下機能に障害を持つ要介護者が増加してきたことと, 歯の喪失を予防する歯科保健対策が不十分であったことに起因する高い歯の喪失率による咀嚼能力の低下が問題である. 一方歯科保健対策の効果が現れてきた若年~壮年者においては, 日常生活における食のプライオリティの低下と, 食事の軟食化に伴う咀嚼回数の減少が問題である. 歯科医療を通して高齢者の咀嚼機能を保持することは, 食を介して全身の健康を維持するとともに, 健康感や生活の満足感を通じて生活の質を向上させ, 健康寿命を延ばすことに繋がる. また食育を推進するとともに, 良く噛んで味わい食事を楽しむ重要性を若い世代に認識させる啓発活動を行うことは, 健全な食生活の実践を通じて生活の質を向上させ, 健康寿命を延ばすことに繋がる.

    Publisher:PHYSIOLOGICAL SOCIETY OF JAPAN  

    The importance of somatosensory information arising from intraoral mechanoreceptors in intraoral sensory discrimination (e.g. detecting position, consistency, size and shape of an object in the oral cavity) should be stressed, since sensory discrimination in the oral cavity are performed without visual information by nature. Nonetheless, there is little information about how the somatosensory information is processed within the cerebral cortex during intraoral sensory discrimination tasks. For this, many studies showed that visual cortical areas are active during tactile discrimination such as Braille reading and blind discrimination of Mah-Jong tiles both in blind and normally sighted humans. The present study was conducted to investigate if visual cortical areas as well as prefrontal area are activated during intraoral form discrimination task by assessing total ([total-Hb]), oxygenated ([oxy-Hb]) and deoxygenated ([deoxy-Hb]) hemoglobin concentration changes using 44 channel near-infrared spectroscopy (NIRS) in normally sighted humans. Among 12 subjects tested (23-62 years old), increase in [total-Hb] and [oxy-Hb] was observed in visual cortical area in all subjects during the task. Also, such task-related increase in [total-Hb] and [oxy-Hb] in prefrontal area was observed in 8 subjects. The findings suggest that visual cortical areas play important roles in intraoral somatosensory discrimination and somatosensory processing patterns within the cerebral cortex may be variable among individuals. &lt;b&gt;[J Physiol Sci. 2008;58 Suppl:S145]&lt;/b&gt;

    Effects of mastication on the jaw-opening reflex (JOR) were studied in awake rabbits. The JOR was evoked by unilateral low-intensity electrical stimulation of the inferior alveolar nerve either chewing or non-chewing side before (control) and during mastication. The entire masticatory sequence (from food intake to just before swallow) was divided into three functionally different masticatory periods (preparatory, rhythmic-chewing and preswallow periods) based on the jaw movements and the related activity pattern of the jaw muscles, and each chewing cycle in each period was further divided into jaw-closing and jaw-opening phases. Then amplitude of the JOR was compared 1) among the masticatory periods and 2) between the stimulation sides (i.e. chewing or non-chewing sides). Overall, the JOR was suppressed during mastication. Although the suppressive effect on the JOR did not differ between the stimulation sides, considerable differences were noted in the suppressive effect among the masticatory periods. During rhythmic-chewing and preswallow periods, the JOR was strongly suppressed in the jaw-closing phase (8 to 20% of the control), but the suppressive effect was phasically weakened (30 to 61% of the control) in the late part of the jaw-opening phase. On the other hand, such phase-dependent fluctuation in the suppressive effect was not observed during the preparatory period. The findings suggest that neural mechanisms modulating the JOR during the preparatory period may be different from other masticatory periods. &lt;b&gt;[J Physiol Sci. 2006;56 Suppl:S189]&lt;/b&gt;

    Previous studies have shown that the jaw-opening reflex (JOR) is modulated during mastication. However in these studies, analyses have been carried out for limited period within the masticatory sequence (i.e. from food intake to just before swallow). Our aim is to study if the modulatory pattern of the JOR is consistent throughout the masticatory sequence in awake rabbits. The masticatory sequence was divided into three masticatory periods (preparatory, rhythmic-chewing and preswallow periods) based on the jaw movement patterns and the activity pattern of the jaw muscles. Electromyographic activity of the jaw-opening muscle (Digastric) and the jaw movement trajectories were recorded. Repetitive electrical stimulation (single pulse, 0.2 ms duration at a rate of 1 Hz, 1.2 times the threshold) of the inferior alveolar nerve was conducted before (for control response) and during mastication to evoke the JOR. The amplitude of the JOR was normalized to the control response and the modulatory pattern of the JOR was compared among the masticatory periods. The JOR was generally suppressed during the rhythmic-chewing and the preswallow periods; the suppressive effect was phasically weakened in the middle part of the jaw opening during the rhythmic-chewing period. On the other hand, the reflex was not only suppressed but also facilitated during the preparatory period. The results suggest that the modulatory pattern of the jaw-opening reflex is different among the masticatory periods. &lt;b&gt;[Jpn J Physiol 55 Suppl:S172 (2005)]&lt;/b&gt;

    Mastication is consisted of various jaw movements commencing with ingestion and ending with swallowing. The progress of mastication is dependent on the interaction of the motor mechanism with variable characteristics of chewed food. In the guinea pig, jaw movement patterns with the progress of mastication have not been clarified under freely moving condition. In this study we recorded EMG activities bilaterally from the masseter and the digastric muscles and simultaneously the jaw movements using a magnetic sensor system. The recordings were made for 1-hour ad libitum fed after 5 hours fast. Masticatory behavior was divided into two stages, (1) an intake-stage representing food intake and transport, and (2) a chewing-stage, food chewing. During the intake-stage, vertical jaw movements were associated with synchronous activations of bilateral masseter muscles. The chewing-stage was characterized mostly by alternate lateral jaw excursions with alternate EMG activity in right and left masseter muscles. Within the chewing-stage, jaw movement patterns altered along with the progress of mastication. These data suggests that masticatory stages in guinea pigs can be estimated by the EMGs and jaw movements. &lt;b&gt;[Jpn J Physiol 55 Suppl:S178 (2005)]&lt;/b&gt;

    The aim of the present study was (1) to investigate how the tongue reflex is modulated during wakefulness and sleep and (2) to examine if modulation of the tongue reflex activities during active sleep is related with respiratory phases or rapid eye movements in the freely moving rabbit. Electromyographic (EMG) activity of tongue muscle was recorded in the genioglossus (tongue-protruder, GG) muscle, and the GG reflex was evoked by electrical stimulation of the inferior alveolar nerve. The current intensity of stimulus was set at 1.5 times threshold to evoke the reflex to evaluate the modulatory mode of GG reflex. Peak to peak amplitude of EMGs in the reflex was compared among wakefulness and sleep stages.GG activity showed a wide variation, some had respiratory-related activity and others did not. However, in all animals, the reflex was suppressed during sleep, and the inhibition was significantly stronger during active sleep than that during quiet sleep. In some cases, the reflex was completely suppressed during active sleep. Furthermore, during this sleep stage, the reflex amplitude during inspiratory phase was larger than that during expiratory phase. On the other hand, the rapid eye movements during active sleep were not related to the changes in the reflex activity during active sleep. Not only basic but also clinical studies have paid attention to loss of tone in upper airway muscles including tongue muscles during sleep. The neuronal mechanisms controlling tongue muscle activity in sleep were discussed. &lt;b&gt;[Jpn J Physiol 54 Suppl:S178 (2004)]&lt;/b&gt;

    Tongue movements participate in oro-facial motor functions including chewing, sucking, swallowing, speech, respiration and so on. Although previous studies reported the coordination of jaw and tongue movements to clarify the patterns of tongue muscle activity, our knowledge as to the functional role of tongue muscles during chewing and swallowing in humans is still limited due to the technical difficulty to record the dynamic activity of tongue muscles. In this study, we recorded the EMG activity of left tongue protruder (genioglossus, GG), jaw-closer and supra- and infra-hyoid muscles during command swallow and natural mastication of test foods as well as rhythmic experimental open-close jaw movements in healthy subjects. For GG recording, the electrode assembly was fabricated on a dental acrylic resin. During command swallow, the subject was required to swallow test foods in different postures which were upright and head inclined w/ and w/o body reclinced to test the effects of head and body postures on the tongue activity. The activity pattern of GG muscle was different among the postures. During experimental rhythmic open-close jaw movements, all the muscles recorded were well-coordinated while the coordination was not observed in the case of natural mastication. Particularly, the GG activity did not always show the rhythmicity. The results suggest the variability of human tongue activity during mastication and swallowing. &lt;b&gt;[Jpn J Physiol 54 Suppl:S179 (2004)]&lt;/b&gt;

    The recent literature on the neural basis of semi-automatic movements such asmastication and swallowing has emphasized the crucial role of brainstem pattern generators in their genesis and regulation. While much less emphasis has been given to the role of higher brain centers, it has been shown that rhythmic jaw movements and swallowing can be evoked in primates by intracortical microstimulation (ICMS) as well as by electrical surface stimulation or transcranial magnetic stimulation of the lateral part of the pericentral cortex of both hemispheres, including the primary face motor cortex (face MI), the primary face somatosensory cortex (face SI), the principal part of the cortical masticatory area (CMA) /swallow cortex, and the deep part of CMA/swallow cortex. Furthermore, recordings of single neuronal activities and ICMS-evoked movements and EMG activities indicate that each of these cortical regions appears to have distinct sensory input and motor output patterns related to rhythmical jaw movements and swallowing, and many neurons in these areas show ingestion-related firing patterns, including activity associated with mastication and swallowing. Recent studies on the behavioral alterations using cold block technique on CMA/swallow cortex, face MI, and face SI indicated the peculiar effects on mastication and swallowing. Bilateral cold block of CMA/swallow cortex was associated with masticatory deficits, reflected as impaired food intake or manipulation and difficulty in carrying out a sequence of masticatory cycles, and alterations of the food-preparatory phase and masticatory and swallowing-related EMG patterns of jaw, tongue, and swallow muscles. Cold block of face MI markedly affected the ability of the monkey to carry out mastication and swallowing. The masticatory deficit was characterized by a significant elongation of the total masticatory time, including in particular elongation of the food preparatory phase. The coordination of the jaw- and tongue-muscle activities was severely disrupted during the food preparatory phase. Although cold block of face MI elongated the duration of the preswallow phase, but it had no significant effect on swallow duration or the EMG parameters during swallowing. Cold block of face SI affected to the total masticatory time, which was due principally to an increase in the preswallow phase time. Taking into consideration the above further evidences of effects by cold block of the CMA/swallow cortex, face MI and face SI, these three cortical regions may be differentially involved in the initiation and control of mastication and swallowing.

    To evaluate the activity of jaw closing muscles, we investigated the tonic vibration reflex (TVR) elicited in jaw closing muscles in rats. The experiments were performed on Wistar rats anaesthetized with urethane (1g/kg). The vibration (120-150Hz, 1mm) was applied to the mandible and the reflex activity was recorded bilaterally from the masseter, temporal and digastric muscles. Experiment I: To establish an experiment model, effective parameters such as vibration frequency, direction of vibration, and jaw position (muscle length) to elicit TVRs were determined. Experiment II: Using the established experimental model, We examined effects of hypertonic saline (5%) and mustard oil (20% in mineral oil) injection into the temporal muscle on TVRs. A vibration frequency of 150Hz in horizontal direction and jaw opening position of 7mm apart at the opposing incisor were determined to be the most effective parameters for TVRs. Both chemicals injected into the temporal muscle reduced the TVR amplitude, and the effect of mustard oil was more than that of hypertonic saline. However, the modulatory effect varied among the muscles tested. In conclusion, effective parameters to elicit TVRs were determined and the change in sensitivity of muscle spindles was suspected to be a factor that affect the response of TVRs to noxious stimuli applied to the jaw closing muscles.ラット閉口筋に微小振動刺激を与え誘発される緊張性振動反射(TVR)を指標に閉口筋の興奮性を評価する実験モデルの確立と、この実験モデルを用いて痛み刺激が筋紡錘の活動性にどのような影響を及ぼしているかについて筋電図学的に研究した。実験にはWistar系ラットを用いた。麻酔はウレタン(1g/kg)を静脈内投与して行った。高頻度微小振動(120-150Hz、1mm)を発生する振動モータを用い、下顎骨を振動させることで閉口筋に誘発されるTVR応答を両側咬筋、側頭筋ならびに顎二腹筋筋電図にて記録した。実験Ⅰ)TVR誘発実験モデルを確立するために、振動の頻度、振動方向、開口量について至適TVR誘発条件を調べた。実験Ⅱ)前項Ⅰで得られた実験モデルを用いて、高張食塩水(5%)あるいはマスタードオイル(20% in mineral oil)を片側側頭筋に注入しTVRに与える影響について検討した。至適TVR誘発条件を、振動頻度は150Hz、振動方向は水平方向、開口量は7mmと決定した。5%食塩水あるいはマスタードオイルの注入によって閉口筋に誘発されるTVR応答は変調された。両刺激溶液ともTVR応答は注入前より減弱され、その減弱はマスタードオイルでより強く得られたが、その変調様式には記録した筋の種類によって相違が認められた。以上の結果から、至適TVR誘発条件が設定され、痛み刺激が筋紡錘の活動性を変化させる可能性が示唆された。

    It has been shown in humans that during mastication the head moves rhythmically and coordinately with jaw movements. A neurophysiological explanation for the mechanism of this finding has not been given so far, matter which became the objective of this study. Head movement and EMG of neck(sternomastoid and splenius capitis)muscles were recorded simultaneously in awake unrestrained rabbits during bread and raw rice chewing. Also, EMG activity was recorded in anesthetized rabbits from the sternomastoid and semispinalis capitis muscles during cortically evoked fictive mastication. In voluntary mastication, the rabbits moved their heads rhythmically in a cycle similar to their chewing cycle and in an opposite direction to the jaw movement, Rhythmical EMG activity was observed in the sternomastoid, which showed biphasic activity in the jaw closing and opening movements during bread chewing ; however, during raw rice chewing it was active only in the jaw closing movements. The splenius muscle showed tonic activity and no rhythmic activity was observed regardless of the test food used. In cortically evoked fictive mastication the sternomastoid was activated only in the jaw closing movements. This activity increased when biting on wooden sticks between opposing molars took place. In the semispinalis capitis tonic activity was observed in both events. Rhythmical head movement coordinated with jaw movement was observed during mastication not only in humans but also in rabbits ; this observation indicates that rabbits are appropriate animal models to study head movement during mastication. From the results of this experiment we suggest that the sternomastoid may be reflexly coactivated with masticatory muscles by peripheral inputs such as periodontal afferents and afferents from propioceptors regulating sense of position during jaw opening and closing movements.

    学校給食は、協同の精神を養うのに不可欠な教育的役割がある。障害のある者と障害のない者が「同じ場で共に学ぶ」ことを目指したインクルーシブ教育システムの構築に向けた環境整備が進められてきたが、特別支援学校で提供される食形態と障害児の嚥下機能とのミスマッチによる窒息・誤嚥が関連するアクシデント・インシデントは後を絶たない。本研究計画では、予備実験で確立した喉頭隆起の動きをフォローする3軸センサを根幹に据え、障害児には指示の入りにくい随意運動に依存した機能検査に代わる①新たな嚥下評価システムの開発および ②特別支援学校における児童の嚥下機能計測と食提供の実態調査を行い、嚥下機能と食提供のマッチングを検証することを目指している。研究計画の初年度にあたる令和3年度は、①に該当する新たな嚥下評価システムの開発の着手してきた。予備実験の段階で有用性が期待された3軸センサでの試作モデル開発に加えて新開発のモーメントの検出を実現する6軸センサでの試作モデル開発を実施した。センサを小型化することで、RSST時などに手指が感じる感覚をトレースすることが可能となり、従来までの垂直方向の力に加えて、水平・前後方向の力を可視化することで対象としている喉頭隆起の動きを3次元的に可視化することが可能となった。これに加え、6軸を採用することで、センサ上を喉頭隆起が動く際に生じる“ずれ”の可視化が実現し、さらに多くの情報を得ることに成功している。しかしながら、センサの検出力を最大限に活かすためにその固定方法が難しく、有病者や障害者に現段階で応用出来るシステムとはなっていない。

    In daily meals, pleasant emotions such as "tasty/pleasant" and unpleasant emotions such as "bad/unpleasant" are mixed, and the sensation of "tasty" varies from person to person. This project aims to clarify "how emotions (pleasant and unpleasant) during chewing affect cerebral hemodynamics" with this study. Furthermore, we examined the effects of the intensity of the taste/smell of the food to be chewed and the magnitude of the emotional change on cerebral blood flow changes, respectively. Hemodynamic responses were significantly elevated in the bilateral primary sensorimotor cortex during chewing as compared to resting. Although the hemodynamic responses of wide brain regions showed little difference between resting and gum chewing states, a difference was detected in the corresponding left frontopolar/dorsolateral prefrontal cortex.

    Stress controls are critical to alleviate stress-induced pain in human. However, 亜as we cannot avoid stressful events in our life, it could be appropriate to control adverse stress responses by means of convenient ways, like exercise. This study determined the effect of daily treadmill running on masseter muscle nociception under psychological stress conditions. The results indicated that enhanced masseter muscle nociception indicated by orofacial nocifensive behaviors and neural activities (c-Fos and FosB) in the upper cervical dorsal horn were inhibited by daily treadmill running exercise.These findings supported our hypothesis that daily exercise could have therapeutic and preventive roles on deep craniofacial nociception associated with psychological stress conditions.

    The information resulted from associated society participation and preliminary study led the following facts; fNIRS is able to measure an activated timing precisely with a brain cortex site activated on exercise. In addition, fNIRS is superior in a movement brain activity measurement with spontaneous posture. Particularly, it is superior that the restrictive of subjects is low and that reproducibility is high. The efficacy is demonstrated in a case (children and infants, affected individual) that cooperation is hard to be obtained for testing.The trial using real fNIRS ended a standard task for failure. Reproducibility was low in the same subjects by the task that we planned at first.It was shown that the choice of an appropriate task was important and to evaluate the velopharyngeal atresia function of patients with cleft palate for reproducibility objectively using fNIRS.

    QX-314 with capsaicin has been reported to produce long-lasting block of acute pain. However, little is reported of their effectiveness on neuropathic pain (NP) after nerve injury which involves various biophysical and molecular changes in sensory neurons. In this study the effect of this combination was evaluated under NP and non-NP conditions after inferior alveolar nerve (IAN) transection.
    The magnitude of QX-314 with capsaicin induced local anesthetic block varied under various conditions; however, no block was observed under NP conditions at 2 weeks after transection. Immunohistochemical study revealed that the number of regenerated neurons with transient receptor potential vanilloid 1 (TRPV1) expression gradually increased over time after transection. Unmyelinated neurons expressing TRPV1 regenerated slowly, especially in the presence of NP. In addition, TRPV1 expression shifted to myelinated fibers and this shift was more intense under NP than under non-NP conditions.

    The present study was conducted to clarify the role of sensory information related to feeding behavior on the cognition of palatability as well as crucial cortical area for such a cognitive function. Also, effects of cognition of palatability on feeding behaviors were also studied. Activity of various cortical areas was recorded in the healthy subjects using near infrared spectroscopy(NIRS), when the subjects performed various feeding-related tasks. The results revealed that the right dorsal prefrontal cortex plays a crucial role for the detection of various feeding-related sensory inputs, and its activity may be increased when the subjects recognize favorable tastes. Also using umami taste as a food additive with salty taste may serve not only as a flavor enhancer but also as an enhancer of swallow initiation.

    超高齢社会の現在、寝たきり者や脳血管障害の後遺症で摂食・嚥下機能に障害をもつ患者の増加が問題になっている。
    我々は、摂食・嚥下障害の問題を解決するため、ヒト嚥下誘発システムを考案した。
    嘔吐反射を誘発させないように刺激電極を鼻腔から挿入し、咽頭領域に留置するために、刺激電極の開発から行った。開発当初は小型で強力なサマリウム磁石を用いて刺激電極を咽頭領域に固定する方法を試みた。次に、内視鏡観察下で位置を確認しながら嚥下誘発域と考えられている咽頭後壁部位を電気刺激する方法を研究した。これらの予備実験により、内視鏡を鼻腔から挿入することなく、咽頭後壁の嚥下誘発部位に電極を設置する方法を開発した。また、電気刺激のモダリティもこれまでの予備実験から、Duration 1ms、frequency 30Hzの連続刺激を与えながら、刺激強度(mA)を大きくすることにより、被験者ごとに対応する適切な電気刺激を決めることが出来るようになった。
    本研究で製作したヒト嚥下誘発システムを用い、健康なヒトにおける嚥下誘発の生理学的特徴を調べた結果、嚥下誘発潜時は、動物実験と同様に刺激頻度依存性に頻度が増すにつれて減少することがわかった。しかしながら、嚥下間隔時間は、これまでの動物実験と異なり刺激頻度に依存せず、ほとんど変化がないことが判明した。おそらく本実験のような覚醒下では、電気刺激に対して2回目以降の嚥下反射に何らかの抑制機構が働くのであろうと示唆される。
    本研究で開発されたヒトの嚥下誘発システムは、経鼻的内視鏡を使用しないため、被験者に負担が少ない上、確実に1回目の嚥下反射が誘発できるので、嚥下障害の治療に対して有効な手法の一つになる可能性を持っていると考えられる。

    Sensory information, arising from orofacial mechanoreceptor discharge associated with masticatory movements, has an important role in controlling masticatory movements reflexly. It is also important in detecting position and/or consistency of ingested food. In the present study effects of mastication on non-nociceptive orofacial sensory transmission of the somatosensory pathways were tested. To achieve this, single-unit activities of the face primary somatosensory cortex (face-SI) neurons responding to low-intensity electrical stimulation of the inferior alveolar nerve (IAN) were recorded during mastication in awake rabbits. The entire masticatory sequence was divided into the preparatory period (PP), the rhythmic-chewing period (RC) and the preswallow period (PS). A total of 112 face-SI neurons were tested for the effects of mastication. The responsiveness of most neurons and the JOR were modulated during different periods of mastication. The IAN-evoked activity was attenuated in a majority of the neurons during at least one of the masticatory periods. A considerable number of face-SI neurons showed mastication-related activity although their responsiveness to IAN stimulation was strongly suppressed (i.e. almost "gated out") during mastication. It was notable that mastication-related activity still remained even after the blockage of peripheral sensory inputs in 60% of such neurons. The findings indicate that 1)sensory transmissions of the somatosensory pathways may be modulated during mastication, and that 2)activity of face-SI neurons during mastication may not necessarily be a simple reflection of movement-induced stimulation of orofacial mechanoreceptors, and suggest that somatosensory integration of a texture of food occur within face SI

  • Localization and functional role of interneurons in the brainstem involved in chewing and swallowing

    An electrophysiological study was performed in awake and anesthetized animals as well as human subjects. In animal experiments, interneuron activities in the brainstem were recorded with EMGs of masseter, digastric and genioglossus muscles. Electrical stimulation was applied in the inferior alveolar and superior laryngeal nerves to evoke the jaw reflex and swallowing reflex, respectively, while the cortical masticatory area was also stimulated to evoke the fictive mastication. Interneuron and/or muscle activity was recorded to investigate how they were modulated by the peripheral/central stimulation. It was very difficult to record interneuron activity because they were very sensitive to the respiration which was also modulated by the stimulation. We, therefore, moved our eyes to the output system to understand the function. In chronic experiments of animals, changes in jaw reflex responses were evaluated during chewing and swallowing. The results showed that the reflexes were suppressed not only during chewing but also during swallowing, and the modulation during swallowing was moderate as compared to that during chewing. The results suggest that the modulatory inputs to motoneurons exist from the chewing center and swallowing center independently. On the other hand, in humans, modulatory pattern was investigated in the EMG activity of the genioglossus muscle which was one of the extrinsic tongue muscles and was known to critically function as making the food bolus and transporting it through the oropharynx to the esophagus. the anterior and posterior portions of tongue were modulated by the peripheral inputs in a different manner. It may contribute to completion of ingestion.

    Mechanical stimulation to pharyngeal and/or laryngeal region has long been believed to elicit swallow reflexively irrespective of the cortical situation. However, videofluorographic (VF) study has revealed that some food may be transported to the pharynx during mastication. Interestingly, the bolus dropped in the pharynx does not elicit swallow till the chewing process is completed. The project was thus designed to seek possible cortical regions which could affect swallowing center, in which magneto-encephalogram and VF were applied for human subjects and kinesiological and electrophysiological methods for animals.
    In rabbits, the ingestive behavior, from food intake to swallowing, could be recorded and identified. The coordination between tongue and masticatory muscles and the role of facial (cheek and lip) muscles during mastication were clarified. To seek a possible cortical region for swallowing, rabbit's cortex was systematically stimulated. Then the region, where swallows were facilitated or inhibited during chewing, was identified. However, no concrete region where the swallow could be elicited solely was identified. We believe that in animals with crudely developed cortex, the region may be limited in a small area or even voluntary swallow itself may not be developed.
    Magneto-encephalogram showed that the cingulate cortex was active for short time about 2 sec preceding voluntary swallows and the insula and operculum were active for long period till swallows occurred. Since cingulate cortex is known as a region relating to emotion, it is concluded that the activation in this region may be related to a recognition process of food. Insula and operculum is known to have a direct connection with the swallowing center, thereafter, the region may be the main one for cortical elicitation of swallows. VF studies revealed that humans swallow two or three times when they clear the mouth of mouthful food as has been reported in animal studies.

    The aim of this research was (1)to investigate the neurophysiological characteristics of premotor neurons which are involved in the masticatory function and (2)to investigate how the activity of jaw, tongue infrahyoid motoneurons are coordinated during mastication.
    During fictive mastication in the anesthetized animal, the styloglossus (tongue-retruder, SG) and masseter (jaw-closer) muscle activities were increased very significantly when the wooden stick was applied between the molar teeth. This may be due to the stimulation of the periodontal mechanoreceptors and also the muscle spindles.
    During natural mastication, activity of masseter, digastric (jaw-opener), mylohyoid (suprahyoid, MH), SG and genioglossus (tongue-protruder, GG) muscles were recorded. Each masticatory cycle had three components including the fast-closing, slow-closing(SC) and opening(Op) phases. The MH muscle exhibited double-peaked bursts during the Op phase. The MH burst in the late part of the Op phase was dominant on the non-chewing side during pellet and bread chewing. The SG muscle also exhibited double-peaked bursts in one masticatory cycle. During pellet and bread chewing, the SG bursts during the SC phase were significantly larger on the chewing side than the non-chewing side. These bursts were also dominant during pellet chewing as compared with banana chewing. The results suggest that the suprahyoid and tongue muscles could play a critical role in completing mastication.
    Regarding the premotor neurons projecting to the trigeminal, facial and hypoglossus motor nuclei, no interneuron was found to project to more than two nuclei with bifurcation. Although many premotor neurons receive inputs from peripheral nerves, these interneurons do not seem to control the coordination of jaw, tongue and facial movements during mastication, but just relay the inputs from the masticatory central rhythm generator in the brain stem.

    実験には主にウサギを用いた。前年度の片側および両側大脳皮質咀嚼・嚥下関連領域の可逆的破壊に伴い摂食・嚥下運動が受ける影響を調べる実験を遂行中、行動学的には片側の大脳皮質顔面運動野の冷却は、咀嚼・嚥下運動を強く障害しないことを示唆するデータが得られた。そこで、片側皮質が不活化されると他の皮質部位が速やかにその機能を代償するのではないかという仮説を立てた。この仮説を検証するために、顔面運動野の片側冷却と両側冷却が咀嚼・嚥下運動に及ぼす影響の違いを行動学的、筋電図学的解析に加え、下顎運動解析も用いて詳細に検討した。その結果、1)顔面運動野の片側冷却により、動物の咀嚼側は、冷却以前の咀嚼側に関わらず、皮質破壊側と同側(機能残存皮質の支配側)となること、2)顔面運動野の両側冷却により食物の取り込みが著しく障害され、以後の咀嚼運動の遂行が不可能となることが明らかになった。このことは顔面運動野は食物の取り込みや移送に重要な脳部位であるだけでなく、咀嚼側の決定に関与していることを示している。片側運動野の冷却は食物の取り込み行為に影響を及ぼさなかったことから、食物取り込み時の顎・顔面・舌の協調機能は対側の顔面運動野によって速やかに代償されるが、咀嚼側の決定に関する機能は代償されないことが示された。さらに、片側運動野冷却時の対側運動野神経活動がどのような影響を受けるのかについて、実験を行なっている。これまでに記録した運動野神経の内、3)対側運動野の冷却により活動様式を変化させるものが58%で、その内53%は活動が増加した。この結果は、少なくとも一部の運動野神経は正常時対側半球の運動野を介して抑制を受けていることを示唆している。また、4)対側皮質冷却の影響を受けないニューロンの87%は口腔領域に明瞭な受容野を持っていた。これより、咀嚼運動調節における感覚野からの感覚情報の重要性も示唆された。

    本研究により、以下の2点が明らかになった。
    1.ウサギ大脳皮質の口腔・顔面領域の覚醒下での詳細なマッピングにより、ウサギ大脳皮質顔面口腔領域の機能局在・部位局在が明らかになった。
    ウサギでは大脳皮質の機能分化が進んでおらず、皮質のほぼ同一の領域が大脳皮質咀嚼野(CMA)または顔面運動野(face MI)、時に第一次顔面感覚野(face SI)として扱われていた。しかし、本研究で、単一神経細胞活動記録と皮質内微小刺激(ICMS)を組み合わせてウサギ大脳皮質口腔顔面領域の機能的マッピングを行ったところ、face MIとCMAは大きく重なり合っているものの、face MIはCMAより吻内側、CMAはface MIより外側の島皮質よりにそれぞれ独立した領域を持つことが明らかになった。また、face MI内部でも機能的な局在があることが明らかになった。Face MIとオーバラップしたCMAへのICMSにより単純な開閉口運動を主体とするリズミカル下顎運動が誘発され、この運動は自然咀嚼時において動物が食物を取り込んだり移送したりするときに行う下顎運動と類似していた。これに対し、face MIより外側に位置するCMAへのICMSにより側方運動を伴うリズミカル下顎運動が誘発され、この運動は自然咀嚼時において動物が食物臼磨様時に行う下顎運動と類似していた。またface SIはface MIおよびCMAのやや後方に位置し、過去にGould(1986)が発表したface SIの脳地図と類似していた。
    2.Face MIおよびCMA内側部を両側冷却ブロックすることで動物の咀嚼運動、特に食物の取り込みや移送がが著しく障害された。
    このことはこれまで脳幹のパタンジェネレータにより制御され、半自動的に遂行されると考えられてきた咀嚼運動の少なくともある部分は、大脳皮質からの下行性制御に依存していることを示している。

    Swallowing is a primitive function necessary for the life support. Its motor behavior is controlled by a swallowing center, which is located in the medulla oblongata. This center generates highly coordinated motor sequence during swallowing. It is mainly composed of two parts; on e part consists of cells in the caudal region of the medulla and receives peripheral inputs; the other consists of motor nuclei in the ventral region of the medulla containing several cranial nerves, including the trigeminal (V), facial (VII), glossopharyngeal(IX), vagal(X) and hypoglossal(XII) nerves, operating the swallowing related muscies. It is also known that this mechanism receives inputs form other regions, such as respiratory center, chewing center and supramedullary regions. Interactions between the above mentioned regions are particularly unclear. The objective of the present study was to elucidate the interaction between these regions using freely behaving rabbits.
    It is concluded that advanced coordination may exist between the swallowing center, chewing center and supramedullary region. A hypothetic interaction between them is summarized.
    1)The swallowing center could not be under the fill control of the chewing center, but the generation of swallows might be controlled or synchronized by the chewing center.
    2) Conversely, the swallowing center might reset the chewing rhythm so that the chewing movement was slowed and the next chewing cycle began in the O_2 phase.
    3) The supramedullary region might send a tonic excitatory input to the swallowing center and maintain its excitability.
    4) The swallows elicited both by natural stlmull and the electrical SLN stimuli were concluded to be identical to each other.

    高齢社会への対応もままならないうちに超高齢社会に移行しつつある。このような時代にあって、医療と福祉のあり方が問い直されている。特に寝たきり老人の増加は、医療費や介護費の増加だけでなく、生活の自由を失った本人にとっても不幸なことである。最近、脳血管障害患者のリハビリテーションにたずさわる人たちが、患者の要求に応える形で経管的栄養摂取を口腔からの栄養摂取に切り替えたところ、意識レベルの向上や全身状態の改善に効果が見られたと報告している。このように、医療や介護の現場では QOLの向上を目指して新しい治療方法を模索し、その過程で基礎的な知識にその糸口を求めてきている。このような現状の中で基礎医学を専攻する我々に対しても社会の要望に耳を傾け、少しでも社会に還元できる研究体制を整えることが求められている。そこで、咀嚼・嚥下・唾液分泌・味覚・神経の5つの分野から選別した専門家でその糸口を探ることとした。
    医療機関・介護福祉機関での聞き取り調査、および摂食・嚥下リハビリテーションに従事する専門家の協力を得て口腔機能研究者に対する要望を調査した。その結果、(1)咀嚼運動と嚥下の関連、(2)唾液分泌促進方法、(3)口腔内食塊移送における舌の役割、(4)嚥下の誘発域、(5)嚥下機能に適した食塊の大きさ、など口腔機能に関する具体的な研究テーマが提示された。この点をふまえ、カナダのトロント大学歯学部を訪れカナダにおける摂食・嚥下機能障害に対する基礎的研究の動向を調査した。その結果、歯学部で直接研究・教育を行ってはいないものの、リハビリセンターでは歯科医が積極的に治療・研究に従事していることがわかった。この点では日本の対応も決して遅いものではなく、この分野の研究を推進することで世界に先駆けた成果をあげられる可能性が示された。

    We have been studying trimgeminal motor behaviors such as chewing, swallowing and jaw-reflexes using chronic animal models. Current project includes the behavior during sleep. In these studies, the investigator had to wait a chance to deliver stimulus and to record data by monitoring the biological data on a screen. Since the monitoring system was set beside the animals, the investigator had to stay there quietly, or a special room may be required at the next door. If the remote operation is available far from the animals, investigator can stay in her/his office. Since the recording does not take place all the time, the operator might utilize the rest of time for other work. The present study has been designed to develop a Java-based data acquisition and analyzing program that can be operated via a computer network from anywhere a client computer is available. A pilot study was carried out as follows : 1) a conventional analog data acquisition and analyzing program was adapted on the network ; 2) behaviors of the animal were monitored by client computers placed in an office ; and 3) telemetric data analyzing system, which is compiled by Java, was developed and tested. Hardware (client computer and network) was found not to be able to handle physiological data on real-time, whereas the Java-based system enabled us to operate instruments such as a stimulator, amplifier etc. under monitoring biological signals. Since programs compiled by Java can be used under any kind of operating systems, operators can use Windows, Macintosh, and Unix machines as a client computer. The results showed a possibility that telemetric laboratory, Which we have designed, may become one of the powerful methods in neuro-physiological studies in the near future.

    Afferent signals arising from the oral, pharyngeal and laryngeal structures may have important roles on the initiation of swallow. In this study, we sought the effects of taste and temperature on swallowing reflex in humans, in which swallowing behavior was recorded and swallow difficulty was evaluated. A thickening agent, that is stable in the physical properties, was employed as the test food. In case of the normal subject, both the parameters of taste and temperature were found to affect swallow difficulty, however, they did not affect the swallowing behavior, such as muscle activities and laryngeal movements. The result suggests that thickening agents prepared at higher temperature than oral temperature and with taste may make easier the initiation of swallowing reflex.
    Swallowing reflex may be initiated when food bolus is transferred from the oral cavity to pharynx. Although superior laryngeal nerve (SLN) stimulation does elicit swallowing in the anesthetized animal, mechanical stimulation around the pharynx may not elicit swallowing in healthy humans. Rather gag reflex is pedominant. In case of CP patients with difficulty in swallowing, cold stimulus to the pharynx is believed to make the swallow easier. Thereafter, we hypothesized that cortex may have an important role on the initiation of swallowing. We thus compared the threshold of SLN stimulation for swallowing during anesthesia and awake in the chronic preparation. A positive result was obtained in that the threshold decreased with lightening the depth of anesthesia, however it increased when the animal was in the awake and rest stage.

    実験には麻酔したウサギを用いた。γ運動神経細胞の同定方法を確立するため、三叉神経運動核背外側部(閉口筋運動ニューロンプール)において咬筋伸張刺激に対し最大の反射性活動が認められる部位からマルチユニット神経活動を記録し、咬筋に刺入した2本のワイヤー電極を介する咬筋神経刺激に対する応答を調べた。その結果潜時1〜1.2msの複合活動電位が記録された。この複合活動電位は明確な二峰性を示さず、逆行性刺激に対する応答潜時のみではα、γ両運動神経を区別することが困難であることが示唆された。そこで同部位よりシングルユニット活動を記録し、便宜的に咬筋神経の逆行性刺激に対する応答潜時が1.5ms以上(長潜時群)のニューロンと1.2ms以下(短潜時群)のニューロンについて発火様式を比較したところ以下の結果が得られた。
    1.長潜時群のうち多くのものに高頻度の自発放電がみられたが、短潜時群にはみられなかった。
    2.下顎の受動的開口に対し長潜時群はリニアな応答を示さなかったが、短潜時群は開口に一致して発火し、繰り返しの開口によってしばしば自発放電をするようになった。また、その際にも開口刺激に対する応答性は失われなかった。
    3.長潜時群のうち約半数のもので体幹や尾に対する繰り返しの触刺激に対して持続的に発火頻度が増加した。この応答は麻酔は浅いほど顕著に認められた。短潜時群にはこのような応答は認められなかった。
    4.電極位置の操作により短潜時群のうち多くのものは1mV以上の電位で活動を記録することが可能であったが、金属電極を用いた場合、長潜時群を活動を500μV以上の電位で記録することは困難であった。
    これらの結果とネコにおいてγ運動神経活動を記録したSessle(1976)の報告とを比較すると、本研究で観察された長潜時群がγ運動神経に相当すると考えられた。覚醒動物でのγ運動神経の記録については今後の課題である。
