title: [Laterality of the facial MT change as the response to oral stimuli including oral sensation or dental pain].
abstract: Minor Tremor (MT), spontaneous about 10 Hz oscillation on the body surface, can be an effector index of physiological reflex behaviors. Many investigations have been made from the thumb balloon surface. Few investigations have been made from the facial surface. No investigation has been made on the laterality of the facial MT. This investigation has been focused on the last problem. The reflex arc has been supposed in order to understand the change of MT described here; the afferent signal is discomfort oral afferent, the efferent route is neuromuscular oscillative system for MT, and the reflex centre is emotional system. When oral discomfort afferents are increased, histogram pattern of facial MT is changed. Control pattern of MT is characterized by unimodal pattern. This pattern changes in parallel to the change in afferent signalling. The side that these MT changes occur is taken with reference to the side that the oral afferents originate. The side relation is also discussed.
