Site of Nerve Division Affects Pain-Related Behavior and Spinal Cord Glial Proliferation after C7 Neurotomy in a Rat Stroke Model

Figure 2

C7 neurotomy procedure. (a) A midline incision on the back of the neck is made. (b) The C5-T1 brachial plexus fully exposed (the black arrow indicates the C7 nerve root). (c) The C7 nerve measured distally relative to the intervertebral foramen (each marking = 1 mm). (d–f) The C7 nerve is resected at 0, 2, or 4 mm according to the subgroup. After neurotomy, the C7 nerve stumps are slightly retracted.
