LECTURES ON THE CENTRAL NERVOUS SYSTEM. 



Internal to the restiform body, which at this level begins 

 to incline toward the cerebellum, lies the dorsal acoustic nucleus, 

 which, just here, has reached its greatest expansion. The fibres 

 of the direct sensory cerebellar tract pass through it, and a lew 

 of them pass into the acoustic nerve. From its ventral border 

 emerges the anterior acoustic root, which is composed of coarse

fibres. This nucleus is also connected with the upper olivary 

 body. It is possible, however, that these latter fibres do not 

 originate in the nucleus itself, but merely pass through it on 

 their way from the cerebellum. In cats a connection between 

 the superior olivary body and the cerebellum is easily shown. 

 In adult human beings we see numerous thick fibres arising
