Overlap between activity changes during physical touch perception and touch observation in contralateral S1. Overlapping voxels between physical touch perception and touch observation are displayed in purple; overlaps are shown separately for the index finger (upper panel) and the middle finger (lower panel); functional images are masked with an anatomical mask covering contralateral S1 and thresholded at p < 0.001 (uncorrected); functional data are visualized on a normalized T1 image of an individual subject; Pre precentral gyrus, Post postcentral gyrus
