Hippocampal AMPA-type receptor complexes containing GluR3 and GluR4 are paralleling training in the Multiple T-Maze

► The GluR4 receptor is linked to spatial learning and memory in the mouse. ► Hippocampal GluR3 and GluR4 complex levels are paralleling performance in the Multiple T-Maze. ► AMPAR complex rather than subunit levels are linked to spatial memory.
