Part of the structure of animal brains, the cerebellar vermis is a narrow, wormlike structure between the hemispheres of the cerebellum.

Function

It is the site of termination of the spinocerebellar pathways that carry subconscious proprioception.

Recent research on the posterior cerebellar vermis indicates that this particular area of the brain may be linked to the brain's natural ability to integrate and analyze inertial motion. Specialized cells in this area, known as Purkinje cells, are now thought to receive sensory information from the vestibular system of the inner ears and use this to compute information about the body's movement through space.[1]

There are nine subdivisons of the cerbellar vermis. They are the: lingula, central, culmen, declive, folium, tuber, pyramid, uvula, nodulus (ordered from anterior to posterior). A useful mnemonic device to remember these subdivisions is : "Like cats catching dogs for the party up north."

Clinical significance

Dandy Walker malformation is a congenital brain malformation that is characterized by enlarged posterior fossa and in which the cerebellar vermis is absent or present in merely a rudimentary form. It is also commonly associated with dysplasias of brainstem nuclei.
