[Electrotonic interaction of secondary neurons of the carp olfactory bulb]
Abstract
Responses of the olfactory bulb secondary neurons provoked by olfactory tract electrical stimulation were studied in carp, using the intracellular recording technique. Spike responses in most neurons were identified as antidromic. Values of their latent periods ranged from 2.5 to 55 msec. In addition, two kinds of responses with a constant latent period were revealed: pseudoantidromic spikes and low-amplitude fast depolarizing potentials. It is supposed that both kinds of responses are generated by an antidromic spike of the neighbouring secondary neuron electrotonically coupled with the neuron recorded.
