Recordings of event-related potentials (ERPs) were combined with structural and functional magnetic resonance imaging (fMRI) to study the spatio-temporal patterns of cortical activity that underlie visual–spatial attention. Small checkerboard stimuli were flashed in random order to the four quadrant...
