As illustrated in Figure 2, this time window captures theta power associated with motor responses to SW in the left motor area. A very similar estimate was obtained for the AN in the right hand area as well. Alcohol intoxication reduced event-related power to SW in the left motor area, F(1,21) = 19.2, p < 0.001, and to AN on the right, F(1,21) = 10.3, p < 0.01, indicating that it affects motor preparation and execution.
