BOLD and flow signals (expressed as percent change; black = binocular, green = monocular) in response to monocular and binocular visual stimulation, averaged over all subjects (6 subjects × 4 averages per subject = 24 averages per signal). Initial overshoot and poststimulus undershoot are observed in BOLD signal for both monocular and binocular stimulation, as is typical for checkerboard stimulation.
