however , it is likely that reactive ventral root axons originate from neurons situated segmentally in the spinal cord , and do not constitute aberrant sensory fibers , as carbonic anhydrase activity remained unchanged in the l4 and l5 ventral roots after removal of the corresponding spinal ganglia , whereas it disappeared after damage to the spinal cord at the lumbar level , or at a site distal to a ventral root section .
