Maps of primary somatosensory cortex were obtained using multiunit recordings immediately, and 3, 6, 9 and 12 weeks following cord-transection (T12) performed on 6-week-old kittens. Results suggest that cortex responds to the injury in two stages: (1) after 3 weeks, all deprived cortex can be excited by the remaining afferent input with little somatotopic organization: and (2) by 12 weeks, the area of drivable cortex has decreased, but somatotopic organization is present within this region.
