Membrane depolarization occurs due to glutamate dependent activation of Ca-impermeable AMPA receptors, which permits the influx of Na+ ions. The depolarization triggers the removal of Mg2+ from the NMDA receptor pore to facilitate its activation. Therefore, activation of AMPA receptors by glutamate precedes activation of NMDA receptors.
