Nicotinic acetylcholine receptors are activated upon ligand binding which opens the acetylcholine channels and permits Ca2+ and Na+ ion influx depending on the subunit composition and stoichiometry of the subunits. The ratio of Ca2+ to Na+ ion influx varies making the receptors either highly Na+ permeable or Ca2+ permeable.
