Uniformity of blood oxygen level-dependent (BOLD) activity and luxotonicity throughout stimulus representation. A: group-averaged (n = 6) BOLD responses (mean %signal change) to 96% contrast condition in experiment 2 (averaged across all 6 luminance levels) plotted as a function of retinotopic eccentricity within early visual cortex. B: group-averaged 96% contrast condition luxotonicity (linear regression slope estimate) in experiment 2 plotted as a function of retinotopic eccentricity within early visual cortex. Abscissa represents the minimum value of each bin, with data binned on a linear scale. Dashed lines denote the boundaries of the voxel selection region of interest. Data are means ± SE across participants.
