AMPA

noun

: a synthetic amino acid C₇H₁₀N₂O₄ that binds selectively to a subset of glutamate receptors on neurons where the binding of glutamate results in an excitatory postsynaptic potential

an AMPA antagonist

The release of glutamate from sensory terminals evokes fast synaptic potentials in dorsal horn neurons by activating the AMPA-type glutamate receptors.

—Allan I. Basbaum and Thomas M. Jessell, in Principles of Neural Science, 4th edition

also : the subset of receptors to which AMPA binds

Glutamate binds to two types of receptor on the postsynaptic neuron, called AMPA and NMDA.
