Vestibular Vertigoes.—At one time loosely grouped together underthe name Menieres disease, the analyses of later years have showna great variety of these affections depending upon the anatomical sitesof the lesions. One must distinguish between: F. thalatno-corticalis. Nucleus ruber Superior cerebellar peduncle Nucleusdentatus F. olivo-cerebellaris^ F. cortico-pontinus J Central Tegmental( Tract Middle cerebellar peduncle Inferior Olive Fig. 117.—Diagram to illustrate the afferent and efferent connections of the cerebellum with the forebrain. 1. Disease of the peripheral end organ, (a) partial, or (b) complete;these are the vertigoes of partial or complete labyrinthine disease. 2. Disease of the first neurone, (a) paresis, (6) paralysis of thevestibularis. 3. Disease of the primary end nuclei in the medulla and of Deitersnucleus. The latter gives a special symptomatology termed Bonnierssyndrome. 4. Disease in the region of the posterior longitudinal bundle asso-ciated with eye movement vertigoes. 5. Disease of the nuclear region of the eye muscles in the corporaquadrigemina. 6. Disease of the pontine eye nuclei. 7. Disease of central eye paths. 8. Disease of cerebellum. DIS
