The cerebellar vermis (from Latin vermis, "worm") is located in the medial, cortico-nuclear zone of the cerebellum, which is in the posterior fossa of the cranium. The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum, dividing it into anterior and posterior lobes.

Mar 22, 2022 · The vermis (pl: vermes) of the cerebellum is an unpaired medial structure that separates the cerebellar hemispheres. Its anatomy broadly follows that of the cerebellar hemispheres. The vermis is separated into a small anterior lobe and a much larger posterior lobe by the primary fissure.

The cerebellar vermis is a region in the brain involved in cardiovascular regulation during movement, posture changes, and emotional challenges. It plays a role in conditioned bradycardia and heart rate conditioning, and its activity correlates with blood pressure changes in humans.

Aug 10, 2022 · The cerebellar Vermis is located at the center of the Cerebellum’s two lobes, in the Cerebellum’s coriconuclear region. The Vermis relates to body posture and mobility and divides the two cerebellar hemispheres.

The vermis of cerebellum (aka cerebellar vermis) is the narrow, medial portion the two cerebellar hemispheres. It has nine subdivisions. These include the i) lingula, ii) central, iii) culmen, iv) declive, v) folium, vi) tuber, vii) pyramid, viii) uvula and ix) nodulus.

Jul 25, 2023 · When looking at the cerebellum from behind, it has two hemispheres which are joined together by a longitudinal depression running down the midline of both hemispheres called the vermis. The cerebellar cortical surface is convoluted into numerous folia.

Oct 30, 2023 · Bilateral to the vermis (both superior and inferior) are the cerebellar hemispheres. There are several horizontal grooves along both surfaces of the cerebellum that give it a stratified appearance. However, some are more prominent than others and provide ideal demarcations for the lobes and lobules.

Here we report the surprising result that a portion of the vermis receives dense input from the cerebral cortex. We injected rabies virus into lobules VB–VIIIB of the vermis and used retrograde transneuronal transport of the virus to define disynaptic inputs to it.
