| Research Abstract |
Neural mechanisms for the genesis of rhythmic jaw movements (RJM) during sleep remain unknown. We have found that RJM can be induced by the stimulation to pyramidal tract in relation to arousals. This suggests that masticatory rhythm generator can be responsive to facilitatory inputs during sleep and that cerebral cortex can be a candidate structure triggering RJM during sleep.
