The vestibular nerve fibers, after being interrupted in the ves-tibular ganglion in the internal auditory meatus, pass directly to the medulla oblongata, in which to the median side of the corpus 58 INTERSTATE MEDICAL JOURNAL restiforme some divide into an ascending and a descending branch,the latter forming the most median portion of the spinal acusticusroot. Some of the vestibular fibers end in the small cell vestibularnucleus, their continuations, which may be followed down to thehypoglossus, being known as the descending vestibular nucleus(nucleus intercalatus Staderini). Direct continuations of certainof the vestibular fibers also reach Deiters nucleus and the nucleusangularis. These fibers, Jones believes, are from the horizontalcanal only. From Deiters nucleus proceed fibers, on the one hand,to the third and sixth nuclei of opposite sides through the fas-

The vestibular fibers fromthe horizontal canal give off collaterals just before they enterDeiters nucleus. These collaterals, as well as fibers from Deitersnucleus, pass through the inferior cerebellar peduncle (corpusrestiforme) to the three cerebellar nuclei fastigii, globosus, andemboliformis. INTERSTATE MEDICAL JOURNAL 59 In the ramus vestibularis are also fibers from the vertical canals.We have clinical evidence of the fact that these fibers, after enter-ing the medulla oblongata, pass upward to end in a nucleus some-where in the upper half of the pons. From this nucleus, fibers passthrough the • fasciculus longitudinalis posterior to the third andfourth nuclei of opposite sides on the one hand and through themiddle cerebellar peduncle (brachium pontis) to the three cerebellar 8 9 11 10 5 KALE
