Mechanisms responsible for the abnormal glutamate and GABA level in the brain of depressed patients remain to be understood. Current study investigate cerebral metabolism in prefrontal cortex of depressed and resilient mice. Level of glutamate, aspartate, taurine and choline was found to be decreased in depressed mice while resilient mice showed increased GABA without any change in other neurometabolites. Depressed mice are associated with reduced glutamatergic and GABAergic activity.
