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 [Wikipedia: http://en.wikipedia.org/wiki/Accessory_cuneate_nucleus].
