The arbor vitae /ˌɑrbɔr 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 and the fastigial nuclei. It also contains the emboliform-globose and dentate 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]

Godfrey Blount's 1899 book Arbor Vitae was ‘a book on the nature and development of imaginative design for the use of teachers and craftsmen’.[5]
