In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

Lesion was made by current of 1mA, 210s in the dorsal funiculus at the 10th thoracic vertebral level. Behavioral and histological evaluation, HRP and fast blue retrograde labelling method were employed. The eletrolytic current caused bilateral corticospinal tract injury and incomplete paraplegia in hind limbs, and led to a substantial atrophy of corticospinal motoneurons , serving as a reproducible and practical model for research on SCI.
