Study links neural circuit with impaired social function

Stimulating neural activity between the amygdala and the nucleus accumbens — a brain region associated with pleasure — impairs social function even though mice find the stimulation rewarding, a new study published by Vanderbilt researchers reports.

Study sheds light on link between cannabis, anxiety and stress

A molecule produced by the brain that activates the same receptors as marijuana is protective against stress by reducing anxiety-causing connections between two brain regions.

Reversing stress-related anxiety

Inhibiting COX-2 — an enzyme associated with inflammation — could provide a novel therapeutic approach for stress-related psychiatric disorders.

Study finds ‘frozen’ fear response may underlie PTSD

To explore how fear becomes entrenched, VUMC researchers traveled down the precise neuronal pathways in the brains of mice that trigger fear responses, and which normally extinguish the behaviors once the danger has passed.

Six Vanderbilt physicians honored by medical societies

Four faculty members of Vanderbilt University School of Medicine were among 78 physician-scientists inducted into The American Society for Clinical Investigation (ASCI), an elite honor society of physician-scientists from the upper ranks of academic medicine and industry. They are:

Regulating anxiety in the brain

Two brain signaling pathways have overlapping functions in regulating anxiety, suggesting that therapeutics aimed at one or the other will impact both.
