Neural activity in early and late recordings. (A) Average firing rate in each of the variants of the antisaccade task in the young stage, for correct trials in behavioral sessions that were recorded in the first half of sessions in three monkeys with sufficient recordings for this analysis. All responses involve the stimulus appearing in the receptive field (n = 102). (B) Average firing rate for the same neurons as in A, when the stimulus appeared away from the receptive field, requiring a saccade into the receptive field. (C) Average firing rate in the second half of sessions in the young stage. Average firing rate is shown for stimulus appearing in the receptive field (n = 146). (D) Average firing rate for the same neurons as in C when the stimulus appeared out of the receptive field.
