The Dorsal columnmedial lemniscus (DCML) pathway is an ascending tract in the spinal cord that is responsible for relaying sensory information related to touch, proprioception (body position sense), and vibration from the body to the brain. The pathway begins with specialized sensory receptors located in the skin, muscles, and joints, which send signals via peripheral nerves to the spinal cord. The signals then travel up the spinal cord through the dorsal columns, which are two bundles of white matter located on the back of the spinal cord. Once in the brainstem, the DCML pathway crosses over to the opposite side of the body and ascends to the thalamus, a relay station for sensory information. From there, the information is sent to the somatosensory cortex, where it is processed and perceived as touch, pressure, or vibration.
