in a final experiment , sequential double-labelling techniques were used to determine whether the v axons that projected to the vibrissa pad via non-io nerve branches were the result of sprouting by undamaged ganglion cells or arose from neurons that had originally projected into the io nerve , were axotomized by our lesions , and regenerated to the vibrissa pad via another v branch .
