Functional localizer scans. Participants were asked to passively view blocks of face, house, and scrambled face images that were separated by fixation blocks. The numbers (in black font) indicate the first and last MRI acquisition of each block. MRI images that were chosen for the local regional heterogeneity analysis are shown in red (face blocks) and blue (fixation blocks). Due to the lag of hemodynamic responses, for face blocks, the images from n0 + 2 to nm + 2 were used (n0 is the time point when face blocks started, and nm is the time point when face blocks ended), and the images from n0 + 4 to nm were used for fixation blocks to avoid signal overlap from the blocks before and after it (n0 is the time point when a fixation block started, and nm is the time point when it ended).
