The four types of experimental preparation and the regeneration specificity resulting from each. Grafts were either Fresh (F) or Predegenerated for 2 weeks (P), and were either aligned correctly (MM- graft Muscle branch joined to recipient Muscle nerve; CC- graft Cutaneous branch joined to recipient Cutaneous nerve) or reversed (CM- graft Cutaneous nerve to recipient Muscle nerve; MC- graft Muscle nerve to recipient Cutaneous nerve). Vertical bars represent the mean number of motoneurons in each group that correctly reinnervated the muscle branch (black bar), incorrectly reinnervated the cutaneous branch (open bar), or projected axon collaterals to both (striped bar). After 8 weeks of regeneration, PMR was pronounced in the correctly-aligned, predegenerated grafts, but not in other groups.
