Overview

N-Methyl-D-Aspartic acid (NMDA) is a synthetic agonist of the NMDA receptor that mimics the binding action of the endogenous ligand glutamate. The NMDA receptor is a voltage-gated ion channel intimately involved in spatial learning and memory, and perturbing the normal behavior of this receptor system with NMDA exposure has facilitated elucidation of NMDA receptor-mediated activities.
