Figure 7. Non-spatial responses at state transition.

(a) The sensorimotor events on a representative trial. The gray panels mark the events during state transitions – the return saccade to the fixation point and the change in fixation point color preceding the transition to the next state. During these periods of fixation, no targets were present and the monkey could not predict the saccade direction. (b) Non-spatial neural activity was enhanced after the F step. Average neural activity (n  =  96 cells) for the two task conditions aligned on the re-fixation saccade and change in fixation point color. Shading indicates SEM for each 1 ms time bin. The horizontal bars and stars denote a significant difference between the two traces (p<0.05).
