Results of Experiment 1. a, Voxels in the ventral pathway in which the statistical comparison of intact versus scrambled objects reached significance (p < 0.001, uncorrected; group data including all scans) for (1) both grayscale images and line drawings (overlap ROI in yellow), (2) grayscale images but not line drawings (grayscale-only ROI in red), and (3) line drawings only (line drawing-only ROI in blue).b—d, The average percent signal change (from the fixation baseline) for each stimulus type based on the group data from the first two scans in the overlap ROI (b), the grayscale-only ROI (c), and the line drawing-only ROI (d) as defined in the last two scans. Data are reported only from regions in the ventral pathway and not from other regions in the brain (i.e., the parietal cortex) as discussed in Results (see Experiment 1). The error bars indicate SEs on the PSC measured across the four repetitions of each stimulus condition averaged across scans.
