Response suppression delays the planning of subsequent stimulus-driven saccades.

The completion of an antisaccade selectively increases the reaction tiME (RT) of a subsequent prosaccade: a result that has been interpreted to reflect the residual inhibition of stimulus-driven saccade networks [1], [2]. In the present investigation we sought to determine whether the increase in pr...
