Accessory cuneate nucleus

Template:Infobox Brain

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.
