"Most NMDA receptors are found in synapses, where they enhance neuronal connections. However, those located outside the synapse are more associated with processes of toxicity and cell death ...

Although they produce opposite effects on synaptic excitability, both LTP and LTD can occur at the same synapse in response to different patterns of activation of NMDA (N-methyl-D-aspartate ...

Glycine activates receptors for the neurotransmitter glutamate, called NMDA receptors ... a sustained strengthening of activity in the synapse during the learning process.
