Dorsal column medial lemniscal pathway refers to a pathway that carries information pertaining to touch and vibration. It is so named because it is routed up the dorsal aspects of the spinal cord to a white matter tract termed the medial lemniscus that courses through the contralateral side of the brainstem through the medulla, pons, and midbrain to be routed up through the thalamus (ventral posterior nucleus ) and on to the primary somatosensory cortex.
