ROI: Region of interest (Cg: cingulate cortex, Ect: ectorhinal cortex, LEnt: lateral entorhinal cortex, NAcc: nucleus accumbens, PT: pretectal nucleus, PTa: parietal association cortex, RS: retrosplenial cortex, Th: thalamus). Hemisphere: left (L) and right (R). k: cluster size, T: T Student. Glucose metabolism: increase (↑) and decrease (↓). p: p value (unc: uncorrected, FWE: family wise error, FDR: false discovery rate).
