New Study: Understanding Critical Components of the Brain’s Stress Circuitry

A new study conducted by researchers at the National Institute of Mental Health (NIMH) has revealed more about the organization and function of a brain structure that may serve a key role in linking stress detection to the development of adaptive behaviors.

They found that, during stress, dopamine (a major modulator of brain function) triggered a reduction in inhibition of the paraventricular nucleus of the thalamus (PVT). Notably, the disinhibition produced by dopamine made the PVT more sensitive to aversive outcomes.
