Abstract
Preganglionic sympathetic neurons were labelled by retrograde transport of horseradish peroxidase, while catecholamine axon varicosities were marked by the uptake of 5-hydroxydopamine in the intermediolateral nucleus of the rat. The direct synaptic contacts from the catecholamine axons to the preganglionic sympathetic neurons were demonstrated. Catecholamine axons formed symmetric synapses.
摘要
节前交感神经元通过辣根过氧化物酶的逆行运输进行标记，而儿茶酚胺轴突膨体则通过大鼠中间外侧核中5-羟多巴胺的摄取进行标记。已证实儿茶酚胺轴突与节前交感神经元之间存在直接的突触联系。儿茶酚胺轴突形成对称突触。
