Fig. 7: Perisaccadic enhancement of the ST representation and its relationship to the perisaccadic spatial bias.

a Neural responses for three sample neurons to probes appearing at the RF center (top) and near the ST (bottom) over time from stimulus onset, for probes presented during the fixation (green; −400:−200 ms) and perisaccadic (orange; 50:150 ms) windows. Mean ± SEM across trials for each neuron. b Distribution of firing rate differences (perisaccadic-fixation) across 447 neurons for probes at the RF center (top; p = 1.32e−45) and near the ST (bottom; p = 2.73e−15). c Average ST sensitivity index of 352 neurons over time from saccade onset for stimulus delay of 50:100 ms relative to each timepoint. Mean ± SEM across neurons; gray bar shows the analysis window used in d and e. d Comparison of ST sensitivity index in the perisaccadic window (50:150 ms) and fixation window (−300:−150 ms) (p = 0.04). Histogram in upper right shows the distribution of differences. e Comparison of ST sensitivity index in the perisaccadic window using the kernels from the full model vs. those from the reduced model (bias-relevant STUs removed) (p = 3.18e−09). p-values were computed by one-sided Wilcoxon signed-rank test. Histogram in upper right shows the distribution of differences. Source data are provided as a Source Data file.
