abstract：:Systemic exposure to N-methyl-d-aspartate (NMDA) receptor antagonists can lead to psychosis and prefrontal cortex (PFC)-dependent behavioral impairments. Agonists of metabotropic glutamate 2/3 (mGlu2/3) receptors ameliorate the adverse behavioral effects of NMDA antagonists in humans and laboratory animals, and are be...
