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 the upper extremity equivalent of Clarke's column.
