Hippocampus CA1 pyramidal GLU cell | Middle apical dendrite | AMPA | . | The Schaeffer collateral/commissural pathway elicits EPSPs in CA1 that have a large AMPA receptor-mediated component that can be blocked by CNQX (Honoré T et al, 1988 [rat]2 ). Reviewed in (Randall AD and Collingridge GL, 19923 ). EM showed colocalization at axodendritic asymmetric synapses within the CA1 subfield of rat hippocampus. AMPA/NMDA receptor colocalization was found in non-GABAergic dendritic shafts as well as dendritic spines, suggesting that excitatory neuronal transmission in CA1 neurons may generally involve activation of both NMDA and AMPA receptor subunits at a single synapse (He Y et al, 19984 ). Using outside-out patches and a fast application system the properties and distribution of synaptic glutamate receptors an approximately twofold increase in AMPA-mediated current was observed in the dendritic region that receives a uniform density of Schaffer collateral input (100-250um from soma) (Andrasfalvy BK and Magee JC, 20011 ). |
