Abstract

The inhibitory reflex evoked in single motor units in human masseter by lip stimulation was recorded at several joint angles. The pre-stimulus firing frequency of the unit was kept constant. Some modulation of the inhibitory response at different vertical jaw positions (i.e., temporomandibular joint angle) was observed in most masseter units, with the majority of the modulated units being inhibited less when the teeth were closer together. © 1989.
