An example of a contra-switch neuron (no-go type). A, Switch-selective activity in the correctly performed saccade overriding task. Rastergrams and SDFs are sorted by the trial position in each block (n represents the switch trials). In the left column, the saccade target was on the contralateral side for both switch trials (n) and nonswitch trials (n − 2, n − 1, n + 1, n + 2); in the right column, the saccade target was on the ipsilateral side for both switch trials and nonswitch trials. Rastergrams and SDFs are aligned with saccade onset. In the rastergrams, small black dots represent the time of individual action potentials and colored dots indicate the time of cue onset; trials are arranged in order of SRTs. B, Ipsilateral no-go activity in the saccade go/no-go task. Rastergrams and SDFs are grouped by the type of trials (go or no-go trials) and the direction of the target. Rastergrams and SDFs are aligned with cue onset. In go trials (top), red dots indicate the time of saccade onset and trials are arranged in order of SRTs.
