Abstract

Subjects maintained constant firing rates in single motor units of the orbicularis oris inferior muscle while auditory clicks were delivered. Audio-motor reflex magnitudes were extracted from poststimulus-time histograms on each motor unit, and these magnitudes were analyzed in relation to motor unit recruitment threshold. Data on 103 motor units in 3 subjects indicated that the magnitudes of the low threshold units differed from the moderate and high threshold units.
