The arbor vitae /ˌɑːrbɔːr ˈvaɪtiː/ (Latin for "Tree of Life") is the cerebellar white matter, so called for its branched, tree-like appearance. In some ways it more resembles a fern and is present in both cerebellar hemispheres.[1] It brings sensory and motor information to and from the cerebellum. The arbor vitae is located deep in the cerebellum. Situated within the arbor vitae are the deep cerebellar nuclei; the dentate, globose, emboliform and the fastigial nuclei. These four different structures lead to the efferent projections of the cerebellum.[2]
The arbor vitae is subject to pathologies such as a cerebellar hemorrhage. Cerebellar hemorrhages arise from tumors, trauma and arteriovenous malformations among other things.[3] The cells in the arbor vitae could also be infected by pathogens which might cause lasting damage, this in turn could lead to cerebellar ataxia.[4]
