ResumoHow is the human brain organized to enhance or suppress specifi c types of behavior? Can we provide a biological explanation for differences between individuals (and societies) in the behaviors they enhance or suppress? Insights from social neuroscience, brain imaging, and neural network theory suggest which cortical-subcortical interactions subserve enhancing or suppressing classes of behaviors. The brain networks proposed for these functions connect four previous research streams from different disciplines. The fi rst stream is Eisler and Levine’s construction of three separate brain networks for the confl icting behavior patterns of fior fldissociation, and bonding – with the orbitomedial prefrontal cortex playing a crucial role in selecting among these patterns. The second is Newman, Grace, O’Reilly, and others’ work on motor ‘gates’ (in the basal ganglia) infl uenced by contextual signals (from the hippocampus) and/or affective signals (from the amygdala). The third is Cloninger’s clinical schema for interacting character and temperament dimensions of personality, which in
