Palmitoylation-mediated synaptic regulation of AMPA receptor trafficking and function. It is well known that agonists of NMDA or AMPA receptors can elicit seizures in animal or human subjects, while antagonists have been shown to inhibit seizures in animal models, suggesting a potential role for NMDA and AMPA receptor antagonists in anti-seizure drug development.

An exciting primer to the study of glutamate receptors and their central role in neurotransmission, The Glutamate Receptors covers the extraordinary research and significant developments in the decade since the previous books were published ... The main difference between AMPA and NMDA is that only the sodium and potassium influx occur in AMPA receptors whereas, in NMDA receptors, calcium influx occurs in addition to sodium and potassium influx. 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.
