Altered Dorsolateral Prefrontal Glutamate Dynamics During Working Memory in Trauma-Exposed Individuals With and Without PTSD: A 7T Functional Magnetic Resonance Spectroscopy Study

Alex S. Beaver, Sarah E. Whiteman Sitts, Abigail Anne Camden…·Meredith Amanda Reid

This study uses 7T fMRS to examine DLPFC glutamate dynamics during working memory in PTSD, trauma-exposed, and non-trauma-exposed individuals, finding altered glutamate levels and cognitive performance differences.

Prefrontal metabolite alterations in individuals with posttraumatic stress disorder: a 7T magnetic resonance spectroscopy study

Meredith Amanda Reid, Sarah E. Whiteman, Abigail Anne Camden…·Frank W. Weathers

This study uses 7T MRS to find lower glutamate levels in PTSD and trauma-exposed individuals compared to controls, with additional changes in NAA and lactate, and a link between glutamate and depression symptoms.
