Fig. 2.

Electromyographic (EMG) activity of selected muscles for Self-reinnervated animals (SELF-REINNERVATED 1–4) before lateral gastrocnemius/soleus (pre-LG/Sol) nerve cut and repair (left column), 2 wk post nerve repair (middle column), and 5 wk to 2.5 mo post nerve repair (right column). Motor activity during walking is present in the Sol muscle before nerve cut, is absent at 2 wk post-repair, and returns by ~5 wk, with the activity getting more intense by 2.5 mo. The progression shows the denervation brought on by the nerve cut and subsequent motor reinnervation.
