Fig. 4From: Evaluation of two collagen conduits and autograft in rabbit sciatic nerve regeneration with quantitative magnetic resonance DTI, electrophysiology, and histologyAxon density, diameter, and axial diffusivity group differences at and distal to the surgical site. Myelinated axon density (a), diameter (b), and axial diffusivity (c) of the three different nerve surgeries, autograft (AG), hollow conduit (HC), and collagen-filled conduit (CF), compared with the nonoperated nerve. There were no significant differences between groups for axonal density either at or distal to the surgical site. The asterisks indicate statistical significance as indicatedBack to article page
