In honor of heros who have sacrificed, for us, is this new information to help explain how our heros work:

Dopamine reward system of the brain. (A) Dopamine neurons in the ventral tegmental area (VTA) directly innervate the nucleus accumbens (NAc), prefrontal cortex (PFC), amygdala (Amy), and hippocampus (Hip) (de la Mora et al., 2010; Kahn and Shohamy, 2013; Shnitko and Robinson, 2014). As in most neural networks, connectivity between the nuclei goes both ways. Dopamine release from the VTA promotes feelings of satisfaction, pleasure and euphoria, rewarding and motivating behavior. Dopamine release from the substantia nigra in the striatum modulates motor functions. (B) While the neurocircuitry modulating the VTA and NAc is complex, major projections from the PFC, Amy and Hip to the VTA and NAc have been identified (Sesack and Grace, 2010). This is consistent with known modulation of reward system dopaminergic activity being influenced by goal-directed behavior (PFC), emotions and feelings (Amy) and experience/memories (Hip) (Sesack and Grace, 2010).
