The cuneate fasciculus is a bundle of nerve fibers located in the spinal cord. It carries sensory information from the upper body, including the arms and hands, to the brain. This pathway is essential for processing touch, pressure, and proprioception, which helps the brain understand body position and movement. The cuneate fasciculus is part of the larger dorsal column-medial lemniscus pathway, which also includes the gracile fasciculus for the lower body. Together, these pathways enable the brain to receive and interpret sensory information, contributing to our ability to interact with the environment effectively.
