The accessory cuneate nucleus is located lateral to the cuneate nucleus in the medulla oblongata at the level of the sensory decussation (the crossing fibers of the posterior column/medial lemniscus tract).
It receives input from cervical spinal nerves and transmits that information to the cerebellum.
These fibers are called cuneocerebellar (cuneate nucleus > cerebellum) fibers. In this function, the accessory cuneate nucleus is comparable to the upper extremity portion of the posterior spinocerebellar tract.
