Population-averaged trial outcome selectivity during the postrew epoch. A, SEF neurons that fired preferentially on correct trials during the postrew epoch (n = 56) showed, on average, a cessation of firing ∼300 ms after the absence of reward in error trials. B, Neurons that fired preferentially on error trials during the postrew epoch (n = 27) showed, on average, an elevation in firing after absence of reward in error trials. Shaded error bars are SEM across neurons within each subpopulation.
