Figure 7. Additional experiments.
Panels show learning curves for the delayed nonmatch-to-sample task, modified in three ways. (A) (left): long 1000 ms delays. (B) (middle): variable inter-stimulus interval, randomly chosen from 300 to 800 ms. (C) (right): Networks with nonnegative neural responses and separate excitatory and inhibitory neurons (in accordance with Dale’s law). Conventions are as in Figure 1: dark lines indicate median over 20 runs, while gray shaded area indicates the inter-quartile range. See text for details.
