Only the most significant peak within each region of activation is reported, with its corresponding MNI coordinates and Z statistic. A statistical threshold of p < 0.001 uncorrected was used for a priori ROIs; elsewhere, correction for multiple comparisons was made with a cluster threshold of p < 0.05, mixed-effects analysis. Values for hMT+ are shown in bold.
