NIH-supported study in mice could inform treatments of trauma- and stress-related psychiatric conditions.
Scientists have identified an area within the brain’s frontal cortex that may coordinate an animal’s response to potentially traumatic situations. Understanding where and how neural circuits involving the frontal cortex regulate such functions, and how such circuits could malfunction, may provide insight about their role in trauma-related and stress-related psychiatric disorders in people. The study, led by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), a part of the National Institutes of Health, was published in Nature.
“Experiencing traumatic events is often at the root of trauma-related and stress-related psychiatric conditions, including alcohol use disorder (AUD),” said the study’s senior author, Andrew Holmes, Ph.D., senior investigator in NIAAA’s Laboratory of Behavioral and Genomic Neuroscience. “Additionally, witnessing others experience traumatic events can also contribute to these disorders.”
