He argued that the “worm-like appendage” [epiphysis or apophysis] of the cerebellum (nowadays known as the vermis superior cerebelli) is much better qualified to play this role (KÃ¼hn 1822, pp. 674-683; May 1968, vol. 1, pp. 418-423).
The median portion is constricted, and is called the vermis, from its annulated appearance which it owes to the transverse ridges and furrows upon it; the lateral expanded portions are named the hemispheres.

It is defined by hypoplasia of the cerebellar vermis, cystic dilatation of fourth ventricle and hydrocephalus.
Although the publication of Vesalius's anatomical dissections in 1543 would disprove many of these theories, including the role of the vermis, we find an elaboration of Avicenna's arrangement — with vermis intact at the fore — in the early 17th century illustrations of Robert Fludd's treatises (fig. 4.10).
Like the notion of the vermis, the common sense was a particularly "mobile" topic.
Publicius's substitution of the pineal gland for the vermis — an opinion held by the "ignorant and stupid," according to Galen (Lokhorst and Kaitaro, "Descartes 'Theory," 7) — is a notion that may be traced back through a translation by Constantine the African to Ibn al-Jazzar (900 – 980), whose views are otherwise consistent with Costa's.
According to Costa's model, then, one should stand erect with neck extended when recollecting, a posture said to raise the vermis and open the foramen, allowing spirits to flow from the front into the hind portion of the brain (fig. 4.8. left).
