Values are means (±SEM) of peak coordinates in millimeters. N, Number of subjects showing significant clusters of activation; % Overlap with attention activations, Out of the total number of voxels responding to the memory-guided saccade task, the percentage that also responded to spatial attention. L, Left; R, right.
