Chronic Social Stress Changes Brain CRF Levels: The Neural Basis of Stress-Induced Anxiety

Animal StudyPreliminary evidence
The takeaway

Chronic psychosocial stress altered CRF levels in the paraventricular nucleus and central amygdala of rats, with changes correlating with anxiety-like behavior — mapping the neural basis of stress-induced anxiety disorders.

Key finding

Chronic psychosocial stress produced CRF alterations in the PVN and central amygdala correlating with increased anxiety-like behavior, mapping how chr

What the researchers found

Chronic psychosocial stress produced CRF alterations in the PVN and central amygdala correlating with increased anxiety-like behavior, mapping how chronic social stress reprograms the brain's CRF stress system to produce persistent anxiety.

Why it matters

Relevant for neuropeptides, anxiety-mood.
