RESUMO
A synaptic potential elicited by high-frequency stimulation of the Schaffer collaterals was enhanced in hippocampal CA1 pyramidal cells from rabbits that were classically conditioned relative to cells from control rabbits. In addition, confirming previous reports, the after-hyperpolarization was reduced in cells from conditioned animals. We suggest that reduced after-hyperpolarization and enhanced synaptic responsiveness in cells from conditioned animals work in concert to contribute to the functioning of hippocampal CA1 pyramidal cells during classical conditioning.
