We isolated NMDA - R EPSC responses for cortical layer 4 → layer 2/3 (L4 → L2 / 3) projections by recording neurons in L2 / 3 while electrically stimulating presynaptic neurons in L4 during constitutive pharmacological block of other ionotropic glutamate receptors (AMPA and kainate receptors) and GABA receptors.

Biosynthesis of ionotropic acetylcholine receptors requires the evolutionarily conserved ER membrane complex. (inmg.fr)
All taste fibers express ionotropic purinergic (P2X) receptors (Bo et al., 1999; Ishida et al., 2009) that are required for transmission from taste receptor cells to the afferent nerves; genetic deletion or pharmacological blockade of the P2X2 and P2X3 receptors expressed by the gustatory nerve fibers eliminates chorda tympani nerve responses to all taste stimuli (Finger et al., 2005; Ohkuri et al., 2012; Jaber et al., 2014; Vandenbeuch et al., 2015).
