Everyone feels stressed from time to time. While people often learn to deal with stress in a healthy, adaptive way, sometimes people respond to stress in a maladaptive way, which can put them at greater risk for developing mental illnesses. Now, a new studyconducted 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. The study, published online June 18, 2018, appears in Nature Neuroscience.
The paraventricular nucleus of the thalamus (PVT) is a brain structure that has been identified as a player in emotional processing, learning, and in adaptive responses to stress. Although knowledge of the role of this brain structure in stress responses is growing, researchers are still working to understand how this structure is organized and how it connects with other parts of the brain.
