Mechanism of Restoration of Forelimb Motor Function after Cervical Spinal Cord Hemisection in Rats: Electrophysiological Verification

Figure 10

Summary of the results of this experiment. All the rats in the group for the preliminary experiment (those that later received the left C5 segmental hemisection) exhibited contralateral electrical activity in response to the stimulation on one side. Also, at 6 weeks after the C5 hemisection surgery, all 12 rats exhibited CMAPs from both forelimb muscles in response to the stimulation on one side before the additional C2 hemisection. With the rats that received the additional C2 hemisection, only the electric potential on the right side was lost. CAMPs: compound muscle action potentials; Rt: right; Lt: left.
