The ITC plot of a single female subject over the frontal cortex (F3, FZ, F4) and occipital cortex (O1, OZ, O2) with visual (V) and auditory (A) stimuli under right hand response (RHR) and left hand response (LHR). Purple dashed line: Onset of the go stimulus. Black dashed line: Onset of the stop signal. Blue dashed line: Onset of response. The significant and non-significant ITC values are shown in red and green colors. The successful go (SG) trial was elicited only by visual stimuli, and the successful stop (SS) trial was elicited both by visual and auditory stimuli. The SS-SG plots display the ITC under human inhibitory control.
