Summary
A study of Wallerian degeneration in the vestibular fibres was carried out on the adult cat after electrolytic destruction of the nerve at its point of entry in the brain stem. Histological observation was restricted to the ventral part of the lateral vestibular nucleus and the adjacent portion of the descending vestibular nucleus: — the classic insertion points of primary afferent fibres —. Once embedded in paraffin wax and stained by ammoniacal silver (following Nauta and Gygax, 1951), the sections were studied conjointly by light and electron microscopy. Ultrastructural analysis revealed the high density of the silver deposit inside the neurons and its relative rareness in the terminal boutons. As a result the latter were basely identifiable by light microscopy, in spite of their being larger than the preterminal segment of the neuron. These results are compared with those obtained by methods which have undergone similar stringent tests, such as those of Fink and Heimer.
