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

Figure 8

CMAPs (stimulation intensity: 2 T) of rats having undergone additional right C2 hemisection. (a) Immediately after right C2 hemisection, electric potential of the right forelimb was lost in response to the stimulation of the right pyramid, whereas the electric potential of the left forelimb was not lost although the waveform amplitude decreased. (b) Immediately after right C2 hemisection, electric potential of the right forelimb was lost in response to the stimulation of the left pyramid, whereas the electric potential of the left forelimb was not lost although the waveform amplitude decreased.
