Resilience to chronic stress is mediated by noradrenergic regulation of dopamine neurons

Elsa Isingrini et al. Nat Neurosci. 2016 Apr.

Abstract

Dopamine (DA) neurons in the ventral tegmental area (VTA) help mediate stress susceptibility and resilience. However, upstream mechanisms controlling these neurons remain unknown. Noradrenergic (NE) neurons in the locus coeruleus, implicated in the pathophysiology of depression, have direct connections within the VTA. Here we demonstrate that NE neurons regulate vulnerability to social defeat through inhibitory control of VTA DA neurons.
