a Brain-map denoting hippocampus (HC; yellow), nucleus accumbens (NAcc; ventral striatum: purple) caudate and putamen (Cd and Pt; dorsal striatum: Orange), thalamus (Thl; blue). 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 temporal gyrus (MTG) and NAcc across movie events. Default mode network regions of interest: PCC posterior cingulate cortex, AG angular gyrus, MTG middle temporal gyrus, MFG middle frontal gyrus, and mPFC medial prefrontal cortex.
