    pag. Chapter II. On the distribution oe the nerves octavus in THE CENTRAL NERVOUS SYSTEM IN RABBITS 45 1. Methods of investigation. Introduction 45 2. The roots of tlie nervus octavus a. The actual view upon tlie signification of tlie N. cochlearis and the N. vestibularis and their continuation in the lateral and ventral root 18 3. The p'imary systems or tlie root-fhres of the nervns octavus a. The fresh degeneration in the root-fibres taking place after the isolated removal of the cochlea and the initial course of tlie dorsal (lateral) root in the central system 53 b. The fresh degeneration in the root-fibres taking place after the section of the VHP'i nerve and the initial traject of the ventral (medial) root in the central system 55 r. The supposition that both roots send their fibres, though in difterent quantities, in the same paths, is confirmed by the study of the myelinisation of the roots in the rabbit 67 d. The supposition that both roots send their fibres in the corpu.s trapezoides is also confirmed by Gudden's method 59 e. The systema ventrale nervi octavi 61 /. The myelinisation-method ofi'ers the same results as the Marchi-raethod, in regard to the position of the root fibres and secundary fibres in the systema ventrale nervi octavi 64 g. The secundary atrophy confirms the existence ofiootfibres in the systema ventrale 67 Jt. The most dorsally situated root-fibres and Held's intermediary system. 69 k. The longitudinal rootfibres ascending towards cerebellum and metence- phalon 73 /. The rootfibres in the systema dorsale nervi octavi 77 ///. The results of the secundary atrophy and of the myelinisation-method in regard to the systema dorsale nervi octavi 83 n. The nucleus dorsalis nervi octavi 88 0. The portio interna corporis restiformis 93 p. The ])ortio interna in the embryo of the rabbit. Its atrophy after root- section 97 q. The descending octavusroot. The transverse dorsal fibres... 101 4.
