Sustained spike activity of neurones in the visual area (field 17) of the cerebral cortex and its changes induced by microionophoresis of serotonin was studied in experiments on unanaesthetized cats immobilized with diplacine. Neurones of field 17 with sustained activity are characterized by non-rhythmic, low-frequency discharges of a mixed type. 55 per cent of the studied neurones were sensitive to serotonin. They exhibited excitatory, inhibitory and phasic responses. The points discussed are: the importance of intracortical interactions between neurones in mechanisms of generation of their sustained spike activity, and the possible ;nvolvement of serotonin in ;he neurochemical processes of synaptic transmission in the visual area of the cerebral cortex.
在使用双丙烯巴比妥固定的未麻醉猫的实验中，研究了大脑皮层视觉区（17区）神经元的持续锋电位活动及其由5-羟色胺微离子电泳诱导的变化。具有持续活动的17区神经元的特征是混合型的非节律性、低频放电。55%的被研究神经元对5-羟色胺敏感。它们表现出兴奋、抑制和相位反应。所讨论的要点是：神经元之间皮质内相互作用在其持续锋电位活动产生机制中的重要性，以及5-羟色胺可能参与大脑皮层视觉区突触传递的神经化学过程。
