Fig. 4.

Locations of the strongest cortical source (peak pseudo-T) in the 30–60 Hz frequency range as the stimulus rotated around the visual field, for subject AH (top row) and subject SW (bottom row). The central panel in each row shows a close-up of the sources from a coronal view, whereas the smaller panels show the data against a full cross-section of the cortical gray/white matter boundary from coronal (left) and axial (right) views. Each source location is represented in the figure by a ‘clock face’ centered on the location of the peak pseudo-T value, with the position of the line(s) in each ‘clock’ indicating the angular location(s) within the visual field at which the stimulus produced that peak.
