Changes in Glutamate Levels After an FMRI Experiment

MRS measures of brain chemistry are often considered static snapshots. We present MRS data showing an increase in Glutamate levels in the anterior cingulate cortex from baseline after a cognitive fMRI task. The biologic and methodologic implications of these findings are discussed.
