| Abstract: | Postsynaptic responses of neurons of the primordial hippocampus to electrical stimulation of brain structures belonging to the visual and olfactory afferent systems were investigated in frogs (Rana temporaria) immobilized with diplacin. * Short-latency (early) and long-latency (late) IPSPs evoked by both olfactory and visual afferent inputs, most probably activated by different conducting systems, are described. Impulses of different modalities can induce both similar and different IPSPs in a neuron. The conducting systems may have a common interneuron for the visual input and specific interneurons for the olfactory input. IPSPs evoked by visual impulses were similar in location to the early IPSP of the olfactory afferent input. Convergence of the systems of early and late inhibition on one neuron was frequently observed for the olfactory afferent input.M. V. Lomonosov Moscow State University.
