The properties of 2 giant electrically coupled neurones (A10 and P1) identified in the visceral and right parietal ganglia of Lymnaea stagnalis were examined. The active and passive electrical parameters of the neurones, as well as the junction between them were measured. The main peripheral and interneuronal connections of the neurones were demonstrated using both electrophysiological and morphological methods. It is shown that the coupled cells are not neurones of the same function, but they are asymmetrical ones. This finding is supported by the following results: (1) the axonal pathways of neurones A10 and P1 are different; (2) there are significant differences in their afferent and efferent connections; (3) though the electrical junction between them is bidirectional, the junctional electrical characteristics prefer P1-A10 transmission. According to the electron microscopic results both neurones are possible neurosecretory cells. The differences demonstrated between the 2 giant neurones may have significance concerning their role in a special neuronal network.
对在椎实螺内脏和右顶神经节中鉴定出的2个巨大电耦合神经元（A10和P1）的特性进行了研究。测量了神经元的主动和被动电参数以及它们之间的连接。使用电生理和形态学方法展示了神经元的主要外周和神经元间连接。结果表明，耦合细胞并非功能相同的神经元，而是不对称的神经元。以下结果支持了这一发现：（1）神经元A10和P1的轴突通路不同；（2）它们的传入和传出连接存在显著差异；（3）尽管它们之间的电连接是双向的，但连接电特性更倾向于P1 - A10的传递。根据电子显微镜结果，这两个神经元都可能是神经分泌细胞。这两个巨大神经元之间表现出的差异可能与其在特定神经元网络中的作用有关。
