[One approach to the study of heterogeneous convergence in the olfactory bulb].
The experimental model for studying the convergence of the heterotype olfactory receptors on the single secondary neuron of the olfactory bulb is proposed. The secondary neuron with bilateral connections (with both olfactory epithelia) in the animals with fused olfactory bulb may serve such a model. The intracellular recording from these secondary neurons of the fused frog's bulb have revealed the secondary neurons which were activated by a certain odorant stimulation of only the one olfactory epithelium, the same odorant stimulation of the other epithelium did not activate (or inhibit) the neurons. The data obtained show that the inputs on the secondary neurons are heterotype, i. e. show the heterogeneous convergence of sensory information on the secondary neurons.
