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.
提出了用于研究异型嗅觉受体在嗅球单个次级神经元上汇聚的实验模型。在嗅球融合的动物中，具有双侧连接（与两个嗅上皮均相连）的次级神经元可作为这样的模型。对融合的青蛙嗅球的这些次级神经元进行细胞内记录发现，某些气味刺激仅激活一个嗅上皮时，会激活这些次级神经元，而相同的气味刺激另一个上皮时则不会激活（或抑制）这些神经元。所获得的数据表明，次级神经元上的输入是异型的，即在次级神经元上感觉信息呈现异质性汇聚。
