Scalp topography of the laterality effects.

<p>Topographies calculated as the mean voltage contralateral minus ipsilateral, for all lateral electrodes pairs, separately for the three time windows of analysis: the display-locked N2pc (160–260 ms, relative to visual-search display onset), left panel; the display-locked SPCN (400–700 ms, relative to visual-search display onset), middle panel; and the go-signal-locked TCN (180–300 ms, relative to go-signal onset), right panel. The maps in each panel represent the view from the top, from the back, and the two lateral views, respectively. Warm colors represent positive voltages, cold colors negative voltages.
