Anterior Lobe (Lobules I–V)

Lobus anterior cerebelli

The sensorimotor anterior lobe of the cerebellum: the first somatotopic map of the trunk and limbs; regulates gait and posture.

Open in the 3D atlas →All regions Parent structure: Cerebellum

Anatomy

In front of the primary fissure; lobules I–V of the vermis and hemispheres.
Receives input from the spinal cord (spinocerebellar tracts) and from motor cortex (via the pontine nuclei).

Functions

Gait, posture and limb coordination.
The first sensorimotor body map (continuous with lobules V–VI).

Clinical

Truncal and gait ataxia with damage to the anterior lobe (especially the vermis).

In the model

How this structure is defined in the 3D model, and the data source.

SUIT atlas (Diedrichsen et al., 2009) lobule labels; each point of the cerebellar surface was assigned to the nearest lobule just beneath it. Overlap between SUIT and the model’s cerebellum: Dice 0.90.
