A simplified characterization of the Social Behavior Network (SBN) and Social Decision-Making Network (SDMN). Brain areas shaded in dark (LS, BNST, POA, MeA, AH, VMH, PAG/CG) represent the SBN. Brain areas shaded lightly (NAc, Str, VP, BLA, HPC, VTA) represent the additional structures that comprise the SDMN, in which the SBN was modified to include core structures from the mesolimbic reward system toward understanding how the brain integrates valence with processing of social information. The LS and BNST have intermediate shading to indicate that they are included in both the SBN and the mesolimbic reward system. Abbreviations: LS: lateral septum; BNST: bed nucleus of the stria terminalis; POA: preoptic area of the hypothalamus; MeA: medial amygdala; AH: anterior hypothalamus; VMH: ventromedial hypothalamus; PAG/CG: periaqueductal grey/ central grey; NAc: nucleus accumbens; Str: striatum; VP: ventral pallidum; BLA: basolateral amygdala; HPC: hippocampus; VTA: ventral tegmental area.
