We have recorded the firing activities of hippocampal pyramidal cells throughout the classical conditioning of eyelid responses in alert cats. Pyramidal cells (n = 220) were identified by their antidromic activation from the ipsilateral fornix and according to their spike properties. Upper eyelid movements were recorded with the search coil in a magnetic(More)
The object of this work was to determine whether the changes in field activity and neuronal excitability recorded in the hippocampus during eyeblink classical conditioning are induced by the cholinergic input, and their relationships with the conditioned response performance. The pyramidal layer field activity, its response to fornix stimulation and eyelid(More)
