Members of iGluRs such as N-methyl-d-aspartate (NMDA) receptor and α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptor are ligand-gated ion channels that allow Na+, K+ and Ca2+ ionic flux upon binding to glutamate, causing membrane depolarization in neurons (Meldrum, 2000). 1016/s1673-5374(07)60102-9.
