摘要: The cellular localization of monoamines in the spinal cord mouse and rat has been studied with use a fluorescence method for histochemical demonstration certain cate-cholamines tryptamines combination pharmacological approach transection experiments. Strong evidence was obtained view that noradrenaline (NA) 5-hydroxytryptamine (5-HT) are localized special systems nerve tracts which from supraspinal centers descend lateral anterior funiculi to terminate gray matter belong monoaminergic neurons. amines show massive accumulation terminal part fibres. This strongly indicates both serve as synaptic transmitters cord. Many terminals containing NA or 5-HT present horns. They more scarce posterior Terminals kinds highly concentrated sympathetic column where most—if not all—of cells surrounded by them. originate—at least mainly—from tract descending dorsolateral funiculi. fibres suggests they arc identical inhibitory going column.
