Fig. 5: Distinctive profiles across the dSTS and PPC on saccade- or fixation-evoked activation and suppression.

a Examples of perisaccadic high-gamma signals aligned either to saccade or fixation onset. High-gamma signal modulation with different saccade durations was computed to test whether the signal was better explained by saccade (top row) or fixation onset (bottom row). The solid and dotted lines show saccade and fixation onset, respectively. The red crosses are the timing of the activation peak for each saccade duration, and the asterisks are for suppression. For the dSTS, activation timing was well explained by saccade onset, whereas suppression was according to fixation onset (type 1), and vice versa for the PPC (type 2). b Electrode positions either classified as type 1 (cyan) or type 2 (orange). Many type 2 electrodes were in the PPC region, while type 1 electrodes clustered around the dSTS.
