Fig. 2: Correlation between surprise ratings and coactivations in Sherlock.
From: The surprising role of the default mode network in naturalistic perception
Rather than extracting correlations across all brain regions, the analysis was hypothesis-driven, focused on the network of interest (DMN), hippocampus, and two distinct control networks (DAN, Vis), thereby limiting in advance the number of tested comparisons. a Brain-maps denoting hippocampus (yellow), DMN (blue), DAN (red), and Vis (green). b Correlation SFPA—Pearson correlations were calculated between surprise ratings (mean of 45 behavioral participants) and ISFC of each region-pair (mean of 35 fMRI participants), across the time-course of n = 49 movie events. Black outlines denote above-chance correlations at p < 0.05 (corrected), determined by random permutation testing (1000 iterations). Scatterplot illustrates the correlation between mean surprise and mean ISFC of the right middle frontal gyrus (MFG) and angular gyrus (AG) across movie events. Regions of interest: HC hippocampus, PCC posterior cingulate cortex, AG angular gyrus, MTG middle temporal gyrus, MFG middle frontal gyrus, mPFC medial prefrontal cortex, SPL superior parietal lobe, PostC postcentral gyrus, FEF frontal eye field, OTC occipital temporal cortex, ParOcc parietal occipital cortex, PrCv precentral ventral region, VisCent visual central areas, and VisPeri visual peripheral areas.
