information about light touch and proprioception travels in the central nervous system in the
Posterior column–medial lemniscus pathway Posterior columnâ€“medial lemniscus pathway (PCML) (also known as the dorsal column-medial lemniscus pathway (DCML)) is a sensory pathway of the central nervous system that conveys localized sensations of fine touch, vibration, two-point discrimination, and proprioception (position sense) from the skin and joints. It transmits information from the body to the postcentral gyrus of the cerebral cortex.[1][2]
