Labeled corticospinal neurons one year after spinal cord transection.
One year after a T9 spinal cord transection, horseradish peroxidase was inserted into the spinal cord at T3-T4. Only about 7% of the number of corticospinal neurons labeled in control rats were labeled in exactly matched transected rats. This long-term loss of labeled neurons makes cell death the most likely explanation for the failure to identify corticospinal neurons in spinal-cord-transected rats.
