NMDA Receptor Function and Physiological Modulation
... NMDA receptor activation leads to opening of an ion channel that is selective for cations, resulting in the influx of Naþ and Ca2þ ions and efflux of Kþ ions. Although most glutamate receptors are cation selective, few are permeable to calcium ions. Its exceptional calcium permeability is the first ...

AMPA receptor
The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (also known as AMPA receptor, AMPAR, or quisqualate receptor) is a non-NMDA-type ionotropic transmembrane receptor for glutamate that mediates fast synaptic transmission in the central nervous system (CNS). Its name is derived from its ability to be activated by the artificial glutamate analog AMPA. The receptor was first named the ""quisqualate receptor"" by Watkins and colleagues after a naturally occurring agonist quisqualate and was only later given the label ""AMPA receptor"" after the selective agonist developed by Tage Honore and colleagues at the Royal Danish School of Pharmacy in Copenhagen. AMPARs are found in many parts of the brain and are the most commonly found receptor in the nervous system. The AMPA receptor GluA2 (GluR2) tetramer was the first glutamate receptor ion channel to be crystallized.
