It transmits information from the body to the postcentral gyrus of the cerebral cortex . </P> <P> There are three neurons involved in the pathway: first - order neurons, second - order neurons, and third - order neurons . The first - order neurons reside in dorsal root ganglia and send their axons through the gracile fasciculus and cuneate fasciculus . The first - order axons make contact with second order neurons at the gracile and cuneate nuclei in the lower medulla . The second - order neurons send their axons to the thalamus . The third order neurons arise from thalamus to the postcentral gyrus . </P>

Information about light touch and proprioception travels in the central nervous system in the
