The arbor vitae refers to the cerebellar white matter
It's in the cerebellum. When cut in half it looks like an upside down tree, hence arbor vitae.
The white matter in the cerebellum is called 'arbor vitae,' meaning 'Tree of Life.' The name refers to the appearance of this part of the brain as branches on trees extending out. Within the arbor vitae are cerebellar nuclei, which receive excitatory inputs from nerve fibers.
