The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (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 ...
The white matter of the cerebellum is known as the arbor vitae (tree of life) because of its branched, tree-like appearance. Embedded within this are four deep cerebellar nuclei . The cerebellum can be divided according to three different criteria: gross anatomical, phylogenetical, and functional.
Embedded within the white matter—which is sometimes called the arbor vitae (tree of life) because of its branched, tree-like appearance in cross-section—are four deep cerebellar nuclei, composed of gray matter. [14] Connecting the cerebellum to different parts of the nervous system are three paired cerebellar peduncles.
The cerebellum is structured in a similar manner as the cerebrum, with a superficial mantle of cerebellar cortex, deep cerebellar white matter (called the "arbor vitae") and aggregates of grey matter surrounded by deep cerebellar white matter (dentate nucleus, globose nucleus, emboliform nucleus, and fastigial nucleus).
The inferior cerebellar peduncle carries many types of input and output fibers that are mainly concerned with integrating proprioceptive sensory input with motor vestibular functions such as balance and posture maintenance. It consists of fibers from the four spinocerebellar tracts that enter the cerebellum:
The cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1]Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain.
A shift in the visual field affects an individual's spatial recognition. The leading research would suggest that the flocculus aids in the synchronization of eye and motor functions after a visual shift occurs in order for the visual field and the motor skills to function together.
