It is part of the somatosensory system and runs in parallel with the ventral spinocerebellar tract. Proprioceptive information is taken to the spinal cord via central processes of dorsal root ganglia (first order neurons). These central processes travel through the dorsal horn where they synapse with second order neurons of Clarke's nucleus. Axon fibers from Clarke's Nucleus convey this proprioceptive information in the spinal cord in the peripheral region of the posteriolateral funiculus ipsilaterally until it reaches the cerebellum, where unconscious proprioceptive information is processed.

This tract involves two neurons and ends up on the same side of the body.
