Fig. 3: Uncertainty and saccade direction.

a Directional selectivity. (Left) PSTH of activity aligned on saccade onset, pooled across reward probabilities for the geometry depicted in the cartoons (mask inside the RF and saccades toward (solid) and away (dashed) from the RF). The traces show mean and ±2 SEM for all cells with sufficient trials in each condition (saccade away, n = 68; saccade toward, n = 52). (Right) Directional selectivity by reward probability. Time-resolved regression coefficients capturing the effect of saccade direction (βDIR) in the same trials as left panel separated by reward probability (mean and ±2 SEM across cells with sufficient trials; 0%; n = 31; 50%: n = 26; 100%: n = 21). Gray bar along the x-axis indicates time window used for statistics. b Effects of reward and uncertainty for saccades away from a mask in the RF (cartoon). PSTHs (top) and reward and uncertainty coefficients (bottom) aligned on saccade onset (mean and ±2 SEM, n = 26 cells with sufficient number of trials). Other conventions as in Fig. 2. The correlation of UNC and REW regressors ranged between −0.04 and 0.1, and was never significant. Source data are provided as a Source Data file.
