Representative nerve stimulation-induced CMAPs of the biceps brachii. Each panel contains typical responses to low (5 mV) and high stimulus strength (11 mV). (A) From the contralateral control nerve of an EEN-2 months rat. (B–F) From the experimental nerve with B and C from EEN-2 months and 3 months, respectively, and (D–F) from representative animal 2, 3 and 6 months following ESN, respectively. Arrows in D and E point to the small CMAP responses recorded following a long delay after stimulation. The stimulation was delivered above the neurorrhaphy site and recording was done at the biceps brachii.
