Summary of hemodynamic response function metrics of the M and P responses within VI

	Mean P/M Ratio	SD	P Value	95% Confidence Interval
% Contrast	0.89	0.23	.16	0.74–1.05
TTP	0.88	0.11	.0037	0.81–0.95
FWHM	0.95	0.18	.36	0.82–1.07

Note:—V1 indicates primary visual cortex; TTP, time to peak; FWHM, full width at half maximum.
