Lack of effect of ketamine on cortical glutamate and glutamine in healthy volunteers: a proton magnetic resonance spectroscopy study.
Ketamine is a N-methyl-D-aspartic acid (NMDA) antagonist that has been associated with temporary clinical improvement in patients with depression. Studies using magnetic resonance spectroscopy (MRS) have shown that major depression is associated with decreased levels of glutamate and glutamine (Glx) in the anterior cingulate cortex, which normalize with clinical recovery. The present study aimed to test whether a ketamine infusion would increase cortical Glx levels in healthy volunteers. Heal...Expand abstract
