The N-methyl-D-aspartate receptor (also known as the NMDA receptor or NMDAR), is a glutamate receptor and predominantly Ca 2+ ion channel found in neurons. The NMDA receptor is one of three types of ionotropic glutamate receptors, the other two being AMPA and kainate receptors.
Dec 11, 2022 · The N-methyl-D-aspartate (NMDA) receptor is a receptor of glutamate, the primary excitatory neurotransmitter in the human brain. It plays an integral role in synaptic plasticity, which is a neuronal mechanism believed to be the basis of memory formation.

NMDA receptors are neurotransmitter receptors that are located in the post-synaptic membrane of a neuron. They are proteins embedded in the membrane of nerve cells that receive signals across the synapse from a previous nerve cell. They are involved in signal transduction and control the opening and closing of ion channels. They are believed to pla...
NMDA receptors are proteins that are embedded in the membrane of post-synaptic neurons. 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 recepto...
The NMDA receptor is involved in the long-term potentiation of an action potential. Full activation of NMDA receptors is both voltage-gated and ligand-gated. The ion channels will only open if the post-synaptic membrane has already been depolarized, and the neurotransmitters glutamate and glycine are attached. There is a voltage-dependent Mg2+ bloc...
Glutamate is an excitatory neurotransmitter involved in many functions including learning, the formation of new memories, and movement. It is the most common excitatory neurotransmitter found in the brain, and thus likely plays a crucial role in normal brain function. Some neurodegenerative conditions may be linked to overexpression of glutamate re...

Learn about NMDA receptors, proteins that are embedded in the membrane of post-synaptic neurons and receive signals from glutamate and glycine. Find out how they are involved in learning, memory, and long-term potentiation, and how they are regulated by voltage and antagonists.
NMDA receptors (NMDARs) are glutamate-gated cation channels with high calcium permeability that play important roles in many aspects of the biology of higher organisms. They are critical for the development of the central nervous system (CNS), generation of rhythms for breathing and locomotion, and the processes underlying learning, memory, and ...
