Effect of buprenorphine on the return of nerve conduction. Electrophysiological studies were performed on animals at 7 and 14 DPI. Transcranial magnetic motor evoked potential (tcMMEP) tracings of sham animal not treated with buprenorphine (A) and treated with buprenorphine (B) at 7 days after the surgery showed normal responses after stimulation. Injured animals not treated with buprenorphine (C) and treated with buprenorphine (D) showed no response after stimulus as expected at 7 DPI and 14 DPI (E and F).
