Fig. 2: Perisaccadic activation pattern of active vision.

Post-saccadic neural activity of whole electrodes. a ECoG perisaccadic spectrogram of representative electrodes. The ECoG signals were aligned by saccade onset. Robust activity can be seen in visual areas after saccades. b High-gamma (100–160 Hz) ECoG signals in representative channels. c The magnitude and latency of the high-gamma signal peak from saccade onset. The data from four animals and 96 × 4 channels distributed over the entire lateral cortex (63 cortical areas) are plotted. The electrodes on the right hemisphere are computationally mapped onto the left hemisphere for visualization purposes. The smooth transition of visual information can be seen in the ventral stream. The areas in the dorsal stream (such as the dSTS including the MT, PPC, and dorsal occipital areas) were activated prior to the ventral stream. Statistical assessment of signal modulation by randomization is shown in Supplementary Fig. 1. d Mean latency of post-saccadic neural activity in each cortical region. Error bars showed standard error of the mean. Dots show individual electrodes. MidVis mid-visual areas (e.g., V3, TEO), LIT lateral inferior temporal areas (e.g., TE1, TE2), vSTS ventral superior temporal sulcus (e.g., PG/IPa, vFST), dSTS dorsal superior temporal sulcus (e.g., MST, MT, dFST), DorsalOcc. dorsal occipital areas (e.g., V6, V3a), PPC posterior parietal cortex (e.g., LIP, AIP, Opt). Supplementary Table 1 shows detailed area names included in each region of interest.
