FIG. 8.

The regional distribution of pre-motor extensor carpi radialis longus (ECRL) interneurons in the cervical spinal cord. The number of pseudorabies virus (PRV)-positive cells counted in the dorsal horn (A) and in intermediate gray matter (B) are expressed relative to the number of PRV-labeled motoneurons (± standard error of the mean [SEM]). The number of labeled interneurons in both control (CTRL) and high cervical lateral hemisection (C2Hx) groups was significantly greater (p<0.05) 96 h after delivery of PRV to the left ECRL than at 72 hin both the dorsal horn and in the intermediate gray matter (*); 72 h after delivery of PRV, the number of ipsilateral labeled cells was no different than the number of contralateral cells in either region in both CTRL and C2Hx groups; 96 h after delivery of PRV, the number of ipsilateral labeled cells was significantly greater (p<0.001) than the number of contralateral cells in both the CTRL and the C2Hx groups (#). There was no difference in the number of labeled cells between CTRL and C2Hx groups in either region, at either time point.
