Table 1.

Histology and number of active nerves

Nine cats with a chronic hemisection and two with acute hemisection were studied. The reconstruction from histology showing the extent of damage in spinal cord tissue was obtained for eight of nine cats. For each cat, the number of active nerves (with rhythmic bursts of activity) in each hindlimb is indicated (rows 4 and 5) before and after complete spinalization (“spinal,” rows 6 and 7). The status of three cats did not allow the study of spinal fictive locomotion.
