Definition
Lobule V of cerebellar hemisphere (a.k.a. lobule V[H]) exists as a part of the anterior lobe of hemisphere of cerebellum.
According to Larsell, the anterior lobe contains five lobules (I to V[H]) of the cerebellar hemispheres. These lobules are created due to the emergence of various transverse fissures that extend throughout the cerebellar hemispheres and the vermis in a mediolateral plane. The lobule V of cerebellar hemisphere–along with the lobule IV[H])–are also called as the ‘anterior quadrangular lobule’ (as per the classic nomenclature).
From a functional standpoint, the lobules I to V[H] of the cerebellar hemispheres along with the vermis (a.k.a. anterior lobe), are the major receivers of the spinocerebellar afferent pathways. These tracts bring in sensory proprioceptive information into the cerebellum and make it aware about the movements and positioning of various body parts in real-time. The cerebellum matches and compares this real-time proprioceptive data with the intended motor plan–originally formulated in the cerebrum–thus playing a crucial role in monitoring and fine-tuning the voluntary motor activities, at a subconscious level.
