Figure 2. Time of target discrimination in delayed match-to-sample task.

Figure 2

A. Population peri-stimulus time histograms (PSTH) of dlPFC neurons (N=63). Average discharge rates are plotted for target in receptive field (RF) trials (solid line) and distractors in receptive field trials (dotted line) using correct trials of difficulty level-1. Shaded area along each plot represents standard error of the mean computed across neurons. A black arrow indicates the time of target discrimination. Receptive filed location is schematically depicted as an orange area in insets (receptive field location differed across neurons). Although green targets are used in the insets for illustration purpose, trials with either red or green color scheme are included in the plots. Plotting bin size is 20 ms. B. Population PSTH of LIP neurons (N=62) using correct trials of difficulty level-1. C. Population PSTH of dlPFC using the same neurons as A, but using correct trials of difficulty level-3. D. Population PSTH of LIP using the same neurons as B with correct trials of difficulty level-3.
