We have investigated the topography of cortical regions active during antisaccades in humans by transcranial magnetic stimulation(TMS). TMS was delivered 80, 100, 120 ms after target presentation over various sites on the scalp. A significant delay in saccade onset was induced over the bilateral frontal regions: a region2-4 cm anterior and 2-4 cm lateral to the hand motor area(HMA), and bilateral posterior parietal regions: 6-8 cm posterior and0-4cm lateral to HMA. The regions inducing delay shifted from posterior parietal regions at 80 ms to frontal regions at 100 ms.
