(A) An example of post-saccadic activity observed at the 180° trials of the ODR task. C, D, and R correspond to the cue period, the delay period, and the response period, respectively. The length of the delay period was 3 s. (B) Post-saccadic activity triggered at the initiation of the saccade. The activity of the same neuron as shown in (A). (C) Activity related to spontaneous saccades occurred during the inter-trial intervals. The activity of the same neuron as shown in (A). The curves drawn on B and C are not the average traces of the eye movements but the cumulative curves of neuron activities. Adapted from Funahashi et al. (1991).
