Diversity of Dopaminergic Neural Circuits in Response to Drug Exposure [PDF]

Neuropsychopharmacology, 2016
Addictive substances are known to increase dopaminergic signaling in the mesocorticolimbic system. The origin of this dopamine (DA) signaling originates in the ventral tegmental area (VTA), which sends afferents to various targets, including the nucleus accumbens, the medial prefrontal cortex, and the basolateral amygdala.
