title: Complex synaptic responses of entorhinal cortical cells in the rat to subicular stimulation in vitro: demonstration of an NMDA receptor-mediated component.
abstract: Intracellular recordings from neurones in the medial entorhinal cortex of the rat in vitro showed that the lowest threshold response to stimulation in the subiculum was a long latency, prolonged depolarization, which in extracellular records corresponded to a late, negative DC shift. These responses were reduced or abolished by 2-aminophosphonovalerate suggesting mediation via activation of amino acid receptors of the 'N-methyl-D-aspartate'-type.
