Task effects. a Comparison of match and nonmatch responses in neurons obtained prior to training, when all stimuli were presented passively, and after training, for neurons tested both with the passive fixation and with the active working memory task. Only neurons that exhibited significant elevation of firing rate for at least one stimulus condition, at one trial- epoch were included in this analysis (mid-dorsal: n = 368 pre-training, n = 94 post-training; anterior-dorsal: n = 153 pre-training, n = 24 post-training; posterior-ventral, n = 178 pre-training, n = 22 post-training; anterior-ventral: n = 46 pre-training, n = 47 post-training). Stars indicate significant differences in 1-tailed t-test between pre-training passive and post-training passive measures, or in 1-tailed, paired t-test in post-training passive vs. active comparisons. b Mean Mutual Information values in each prefrontal region. c Mean Fano factor values in each prefrontal region
