Figure 7.

Population-averaged trial outcome selectivity during the percstim epoch. A, SEF neurons that fired preferentially on correct trials during the percstim epoch (n = 8) exhibited phasic modulations 100–300 ms after appearance of the decision targets. B, In contrast, neurons that fired preferentially on error trials during the percstim epoch (n = 12) showed more tonic modulations beginning ∼150 ms after appearance of the decision targets and, in some cases, lasting throughout the remainder of the trial. Conventions are as in Figure 4 except that shaded error bars are SEM across neurons within each subpopulation.
