Selective plasticity of primary afferent innervation to the dorsal horn and autonomic nuclei following lumbosacral ventral root avulsion and reimplantation in long term studies

► L6-S1 ventral root avulsion (VRA) results in plasticity of L1-L2 afferents. ► Avulsed root implantation (VRI) results in partial restoration of L1-L2 afferents. ► L6-Sl VRA and VRI selectively affect afferents of the pelvic autonomic circuitry. ► Fluorogold injection into the major pelvic ganglion labels autonomic cell bodies.
