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

Figure 11

Compensation pathway of the corticospinal tract after the recovery of motor function. Stim: stimulation; Rt: right; cut: left C5 segmental hemisection of cervical cord; short broken line: dorsal corticospinal tract (posterior funiculus); long broken line: ventral corticospinal tract; arrow: sprouting; gray line: activation of the ventral corticospinal tract; arrow head: contralateral additional C2 hemisection.
