Population analysis of disparity test. A, Histogram of SDI pooled across subjects for all neurons (N = 123) showing significant selectivity in the disparity test (ANOVA of the net responses to the four three-dimensional shapes in the test). The last bar in A includes all cells that had an SDI of 4.5 or higher. B, Histogram of SSI for the same population of neurons (N = 123). C, Population PSTH in the disparity test. Mean normalized responses to the preferred (black) and nonpreferred (gray) three-dimensional shape are shown (20 ms bins) for all AIP neurons showing significant selectivity in the disparity test (ANOVA, p < 0.05). The vertical dashed line indicates the first bin with significant selectivity.
