ResumoControl of single motor unit activity in adult human subjects (59–73 kg) was studied by requiring a single spike discharge to a flash of light and recording the resultant reaction time (RT). Experimental sessions without alcohol were followed by ingestion of 20 cm3 95% ethyl alcohol and re-testing the reaction time performance. Median latencies were slower following the intake of alcohol; however, the capacity to respond as defined simply by the ability to produce a motor unit spike was not altered. Electromyographic RT responding also slowed following alcohol, although to a lesser degree than did single motor unit RT.
