Inter-subject synchronization. (a) Pairs of separate viewers also show synchronized cortical responses in regions related to visual and auditory processing during naturalistic viewing, as shown in the unthresholded map of synchronization averaged across all possible pairs of 10 viewers (45 pairs in total). (b) Oxy-hemoglobin timeseries from a seed region in the left superior temporal gyrus (inset) for individual viewers (grey lines) and the group average (black line).
