TMS-EPs are associated with saccade latency on trials after antisaccade. A, TMS-EPs on fast and slow response trials at electrode TP7 (marked with white circle in B), separately shown for the four conditions based on the previous and current tasks. B, Scalp topography of TMS-EPs amplitude within the time window of 20–40 ms after TMS (gray shading in A). In each cell defined by the previous task (rows) and current task (columns), maps are shown separately for fast (upper) and slow (lower) response trials. C, Scalp topography of p values based on paired t test. TMS-EPs at each electrode position were compared between fast and slow response trials. Results are shown separately for the types of previous task (rows) and types of current task (columns).
