The ventral (anterior) spinocerebellar tract carries information about the activity of spinal motor circuits for the lower limb to the cerebellum. Its fibres cross in the cord, ascend on the surface of the lateral funiculus and enter the cerebellum through the superior cerebellar peduncle, where many cross back again, so the information ends up on the same side as it started.

Informs the cerebellum about the activity of spinal motor and reflex circuits, helping coordinate whole-limb movement and posture.
The ventral spinocerebellar tract is affected with the dorsal tract in inherited ataxias such as Friedreich ataxia. Because it runs superficially in the lateral cord, it can be affected by surface compression or demyelination, contributing to ataxia.
Degeneration of both spinocerebellar tracts, contributing to gait and limb ataxia.
Inflammatory damage to the lateral cord, as in multiple sclerosis, that may involve the spinocerebellar tracts and impair coordination.
