nmda

NMDA stands for **N-methyl-D-aspartate**, which is a synthetic derivative of the amino acid aspartate. It acts as a **specific agonist** at the NMDA receptor, a subtype of glutamate receptor in the brain. NMDA receptors are involved in synaptic plasticity, learning, and memory processes by controlling the flow of calcium (Ca²⁺) ions into neurons when activated.
