Dynamic movements of AMPA receptors in and out of the postsynaptic membrane account for, at least in part, the expression of NMDA receptor-dependent changes in synaptic efficacy such as long-term potentiation and long-term depression. Recently some of key molecules and subunit rules involved in AMPA receptor trafficking have been identified. In this update article, we try to highlight what we believe to be the major conceptual problems and unanswered questions in this rapidly moving field of neuroscience.
