N-Methyl-D-aspartic acid (NMDA) receptors are a unique family of iGluRs that activate in response to the concurrent binding of glutamate and glycine. NMDA receptors are central to activity dependent changes in synaptic strength and are predominantly involved in the synaptic plasticity that pertains to learning and memory. A unique feature of NMDA receptors, unlike other glutamate receptors, is the requirement for dual activation, both voltage-dependent and ligand-dependent activation. The The N-methyl-D-aspartate (NMDA) receptors are made up of five subunits that have a similar amino acid sequence to other glutamate membrane receptor classes such as the AMPA (α-amino-3-hydroxy-5-methly-4-isoxazole propionic acid) receptors and the kainate receptors. Glutamate is the principal excitatory neurotransmitter in the basal ganglia acting through ionotropic NMDA, kainate and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and G-protein-coupled metabotropic receptor subtypes. Because glutamate/NMDA receptors are located throughout the brain, glutamatergic models predict widespread cortical dysfunction with particular involvement of NMDA receptors throughout the brain.

The NMDA receptor is one of three types of ionotropic glutamate NMDA receptors are formed by different subunits belonging to two classes: NMDAR1 (NR1) and NMDAR2 (NR2) (3-7).

Channel activation requires binding of the neurotransmitter glutamate to 2012-01-01 The NMDA receptors require both glutamate and depolarisation in order to get activated. During resting membrane potential the NMDA-channel is blocked by Mg2+ ion, and to be relieved from that blockade NMDA receptors require depolarisation, which is provided by the AMPA receptors.

Calcium flux through NMDARs is thought to play a critical N-methyl-D-aspartate (NMDA) receptors, a family of L-glutamate receptors, play an important role in learning and memory, and are critical for spatial memory. These receptors are tetrameric ion channels composed of a family of related subunits. One of the hallmarks of the aging human population is a decline in cognitive function; studies in the past couple of years have demonstrated NMDA receptor subtype of glutamate-gated ion channels with reduced single-channel conductance, low calcium permeability and low voltage-dependent sensitivity to magnesium. Mediated by glycine. May play a role in the development of dendritic spines.

There are two basic types of receptors in the brain; one uses channels for chemical ions that open and close (inotropic) and the other are large proteins that create a cascade of signaling molecules from the membrane down to the nucleus (metabotropic). Different glutamate receptors use both mechanisms. NMDA is a prototypic agonist that binds specifically to the NMDA receptor but not to other glutamate receptors , and has previously been used in cell culture studies . During the stimulation period the cells were kept in D-MEM with or without supplementations (FBS, pen strep, L-Glutamine). NMDA is an unfortunate acronym for N-methyl-D-aspartate, and this amino acid derivative is very similar to glutamate.
