Activation of NMDA receptors by infrequent or unusual activity patterns can recruit AMPA receptors to the cell surface, allowing behaviors to occur without engaging the full neuroplasticity process of building new proteins.

“when the nmda receptor is activated by these infrequent or unusual patterns of activity it can then recruit other glutamate receptors the more typical kind the ampa type receptors to the cell surface and then those receptors can simply bind the glutamate and allow that behavior to occur without this whole process that's involved in neuroplasticity having to engage and do things like build new proteins in the cell build new Machinery Etc”
