Part of the structure of animal [[brain]]s, 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.<ref>[http://www.sciencedaily.com/releases/2007/06/070620122014.htm Purkinje Cells in Posterior Cerebellar Vermis Encode Motion in an Inertial Reference Frame]</ref>
==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.
