Intra-subject synchronization. (a) Seed region (purple sphere) used to extract an exemplar oxy-hemoglobin timeseries during viewing of repeated movie stimuli (b) and mismatched movie stimuli (c) from a single subject’s data (i.e. two repetitions of the movie stimulus). (d) During repeated presentations of the stimulus, the group average of individual viewers’ synchronization maps shows elevated synchronization in regions across the cortical field-of-view, particularly auditory and visual processing regions, as shown in this unthresholded T-map. (e) During mismatched stimulus presentations, the synchronization values are greatly reduced, as shown in this unthresholded T-map. (f) Voxelwise distributions of Pearson correlation values during repeated and mismatched movie presentations.
