Situated immedi- ately beneath the floor of the fourth ventricle, underlying the ependymal gray matter, is a large triangular nucleus of small cells, the nucleus of Schwalbe (NSc), and lateral to this a nucleus containing many large cells, the nucleus magnocellularis of Deiters (ND). Dispersed among the cells of the latter nucleus are many small bundles of heavily mye- linated axons. These two nuclei constitute the vestibular complex. They have assumed, in a general way, the positions occupied in the lower levels by the nuclei of Goll and Burdach. In the topographical relation of these.
