Learn Phase, fMRI Results: Neural Activity in the Amygdala and Anterior Hippocampus Selectively Tracks the Emergence of Knowledge about Social, but Not Nonsocial, Hierarchies

(A) Activity in bilateral amygdala (left panel, coronal section) and bilateral anterior hippocampus (right panel, coronal section) shows a significant correlation with the inference score index in the social domain. Activations thresholded at p < 0.005 uncorrected for display purposes, and shown over average structural image of all participants but significant in amygdala and hippocampus at p < 0.001 uncorrected and p < 0.05 whole-brain FWE corrected at cluster level; colorbar (red-yellow) indicates increasing t values. See Table S1A for full list of activations.

(B) Activity in left amygdala/anterior hippocampus (left panel, coronal section) and right amygdala (right panel, sagittal section) shows a significantly greater correlation with the inference score index in the social, as compared to the nonsocial, domain. Activations thresholded at p < 0.005 uncorrected for display purposes but significant in amygdala and hippocampus at p < 0.001 uncorrected and p < 0.05 SVC corrected; see Table S1B for full list of activations.
