Figure 5.

Plots of decoding accuracy over time indicate the proportion of trials in which sample position (A, B), rule (C, D), and spatial category (D, E) were accurately decoded from population activity patterns measured in successive 50 ms time bins in parietal cortex (red) and prefrontal cortex (blue). Data from monkey 1 (A, C, E) and monkey 2 (B, D, F) are plotted separately. Time bins in which the proportion of correctly decoded trials varied significantly between prefrontal and parietal cortex are indicated by filled circles and sections of the time courses plotted with a thicker line (z test of proportions, α level indicated in each panel).
