FIGURE 5.

Spatial updating within hemifields. EEG topoplots from the world-fixed condition, averaged over trials where subjects indicate that the target remains on the same side as the initial target on the left (Top) and right (Middle). Visually presented targets are initially reflected by contralateralized alpha reductions, and evolve into alpha increases contralateral to the remembered target after motion. (Bottom) Subtraction of left and right target conditions, isolating activity related the target representation.
