Overview of the main brain structures and their connections involved in (a) aggressive behaviour and their serotonergic input from the dorsal raphe and (b) dopaminergic input from the ventral tegmental area. AMYG, amygdala; AVP, arginine vasopressin; cp, caudate putamen; DRN, dorsal raphe nucleus; HAA, hypothalamic attack area; hpc, hippocampus; LS, lateral septum; MRN, medial raphe nucleus; NAcc, nucleus accumbens; ob, olfactory bulb; PAG, periaqueductal grey; PFC, prefrontal cortex; pit, pituitary; SNR, substantia nigra; thal, thalamus; VP, ventral pallidum; VTA, ventral tegmental area.
