Nucleus Cuneatus
The Nucleus Cuneatus is a cluster of nerve cells located in the brainstem, specifically in the medulla oblongata. It plays a crucial role in processing sensory information from the upper body, particularly touch and proprioception. This nucleus receives input from sensory neurons that carry signals from the arms and upper torso.
After processing this sensory information, the Nucleus Cuneatus sends signals to the thalamus, which then relays the information to the cerebral cortex for further interpretation. This pathway is part of the larger dorsal column-medial lemniscus pathway, essential for the perception of fine touch and body position.
