Functional maps demonstrating regions that were more active during the search (warm colors) or matching trials (cool colors).

<p>The event-related averages (bottom panels, corresponding to the labeled arrows in the brain images) show the time course of the activation from the search (red) and matching trials (blue) in the search-specific regions of parietal and frontal cortices. All activations surpassed a whole-brain voxel-level threshold of <i>p</i><0.001 (uncorrected) with a cluster-corrected threshold of <i>p</i><0.05.
