![]() ![]() b For each individual, the average response time series within each ROI was extracted during video viewing. Next, a cortical surface model was reconstructed and parcellated into anatomical units, which are signified by different colors in the cortical parcellation scheme illustrated on the far right. These structures are signified by color in the image demonstrating volumetric segmentation (e.g., the left and right cerebral cortex are shown in magenta and purple, respectively). Segmentation of cerebral cortex, subcortical white matter, and deep gray matter volumetric structures (e.g., hippocampus, amygdala, and putamen) was performed on the high-resolution scan of each individual’s brain volume. a Eighty anatomical regions of interest (ROIs) were derived for each individual using the FreeSurfer image analysis suite. Computing inter-subject time series correlations. ![]()
