Spatial tuning across epochs for non-visually responsive, delay-selective neurons. A, B, Average normalized FR (A) and FF values (B) as a function of radial distance from the RF location for 150 ms windows during the baseline, cue, 400 ms into the delay, 1400 ms into the delay, first flash, interflash interval, and second flash. The box panels along the top show a schematic diagram of the display seen by the monkey during each task epoch. The horizontal magenta lines below the schematic timeline and connected to each box panel indicate the 150 ms window used for analysis. Each point represents the average FR or FF value for the corresponding cue location, and error bars denote the SEM. The dotted lines represent the average baseline value across all six cue locations, and the black outlined points indicate significant deviation from baseline (Wilcoxon's signed rank, p < 0.05). For each tuning function, if the points yielded a significant repeated-measures ANOVA (p < 0.01), the average points for each location were fit to a von Mises, or circular Gaussian function, shown by a continuous solid line. Tuning functions that were not significant according to the ANOVA are shown with a dashed line across the mean of the average values at each location. Conventions are the same as in Figure 3.
