Abstract: | Electrical responses of 25 presumptive hippocampal inhibitory interneurons to stimulation of two afferent systems of fibers, originating in the contralateral hippocampus, were investigated in acute experiments on unanesthetized, immobilized rabbits. Inhibitory neurons were found to have a relatively ineffective inhibitory input as well as a very effective excitatory input. On interaction between synaptic processes during spontaneous and evoked activity the excitatory input clearly predominates over the inhibitory and plays a definite role in behavior of the neurons.A.
