[Fluorescence histochemical identification of axons using the GOLGI method]

Using fluorescence histochemical and GOLGI-methods afferent fibers in the albino rat's dorsal lateral geniculate nucleus (d LGN) have been investigated. We considered the following parameters: diameters of the axons, diameters of boutons, number of the boutons by 100 micrometers axon length. From comparison of the data from histochemical material with the data of the GOLGI-material follows that the noradrenergic terminals are identical with the type-4- and 5-axons. The terminal branching and synaptic contacts of the type-4- and 5-axons are discussed in connection with the aminergic innervation of this nucleus.
