Fig. 5: Identifying the neural correlates of spatial bias around the ST area from neurons whose RFs are located near the ST.

a Bias-relevant STUs and model-predicted response, plotted as a function of time of stimulus from saccade onset (y-axis) and time of response from stimulus onset (x-axis). Shown for ensembles with d < 11 dva (n = 4 ensembles, 94 neurons). b Map of RF centers relative to the FP and ST using all ensembles used in a, and the probe locations around the ST. Prevalence of RF center (colorbar) indicates the percentage of neurons with RF centers in the corresponding location. “Near” probes are the three probes on the side of the ST towards the FP (orange), while the “far” probes are on the other side of the ST (green). c Mean of normalized model-predicted responses (left) and actual neural responses (right) over time from probe onset, for near (orange) and far (green) probes, during fixation (top; −500:−100 ms) and perisaccadic (bottom; −20:10 ms) windows. Mean±SEM across models or neurons in the ensembles; gray bars show analysis windows used in d. d Comparison of actual neural responses to near vs. far probes (n = 94 neurons), for the fixation period (top; p = 5.38e−12) and perisaccadic period (bottom; p = 0.50). p-values were computed by one-sided Wilcoxon signed-rank test. Histograms in upper right show the distribution of differences. Source data are provided as a Source Data file.
