Stimulus epoch activity elicited by “cloud of dots” stimulus is spatially tuned, but less accurate than the animal’s behavior.

(a) Firing rate distribution across putative single neurons during stimulus epoch. (b) Distribution of stimulus selectivity index across all cells active in the stimulus epoch. Blue (lower-preferring, 64/305) and orange (upper-preferring, 54/305) histograms denote cells with significant stimulus selectivity, compared to a shuffle control. (c) Comparison of psychometric (black) with neurometric (blue) curve for best lower-preferring cell. Inset: Comparison of psychometric and neurometric slopes across all single units used for stimulus selectivity analysis. Dashed line indicates unity line. (d) Selectivity index-based choice probabilities in V1 single neurons (see Methods). Cells with significant choice probabilities are shown in blue (3/305) and orange (2/305).
