title: [Electrical characteristics of the granular neurons of the carp olfactory bulb].
abstract: Using the intracellular recording technique the electrical activity of the carp olfactory bulb granular cells and secondary neurons was studied. Early and late EPSP and IPSP were the synaptic responses of granular cells both to the olfactory nerve and olfactory tract electrical stimulation. The comparison of responses of the granular cells and secondary neurons led to the conclusion that the granular cells are interneurons producing post-synaptic inhibition of the secondary neurons. It was supposed that the granular neurons are excited by dendro-dendritic and reccurent-collateral pathways and that the inhibitory synapses are located on the dendrites of secondary neurons which are in contact with the olfactory nerve terminals.
