This study in adult cats demonstrates that primary neurons of all sizes survive following the transection and capping with a polyethylene tube of their peripheral processes in the supeficial radial nerve. The central axonal arbors of these injured primary neurons remain intact and maintain their topographic position across laminae I-VI of the cervical (C6-C8) dorsal horn. In addition, they maintain their synaptic vesicles, some of their synaptic connections and their ability to transport horseradish peroxidase transganglionically.
