Activity patterns of example SEF neurons that encoded past trial outcomes. A, Neuron that fired more after correct trials. B, Neuron that fired more after error trials. Both neurons showed large modulations in firing rate immediately after feedback delivery (postrew epoch, left). These tonic modulations persisted into the start of the next trial (baseline epoch, trial n − 1, center) and were still present at the start of the trial after that (baseline epoch, trial n − 2, right). Shaded error bars are SEM across trials within each condition.
