Truncal ataxia is caused by midline damage to the cerebellar vermis. These symptoms include dysarthria, nystagmus, and hypoplasia of the cerebellum and vermis. This region comprises the vermis and intermediate parts of the cerebellar hemispheres. The alcohol abuse causes degeneration of the anterior vermis of the cerebellum. A narrow strip of protruding tissue along the midline is called the cerebellar vermis. The pontine nuclei project to the cerebellum, specifically the vermis and the paraflocculus. The pyramid is the seventh lobule of the vermis on the superoinferior axis. Both the vermis and the hemispheres are composed of lobules formed by groups of folia. The fastigial nucleus receives its input from Purkinje cells in the vermis. The anterior and posterior lobes are connected in the middle by the vermis. Functionally, the vermis is associated with bodily posture and locomotion. One study used TMS on the vermis of patients with schizophrenia. There is a reference to 'De Vermis Mysteriis' in the 2004 movie, "Hellboy". On April 3, 2012, High on Fire released their sixth studio album, "De Vermis Mysteriis". Sorcerer and author of "De Vermis Mysteriis".
