Nucleus cuneatus

Definition

The nucleus cuneatus is a cluster of sensory neurons located in the lower part of the medulla oblongata, part of the brainstem, that primarily processes touch and proprioceptive information from the upper body and arms before relaying it to the thalamus. It plays a crucial role in the pathway of somatosensory information to the cerebral cortex for interpretation.
