Figure 1. Stimulating electrode implant and anti-nociception.

Figure 1

(A) Schematic drawing of the bipolar stimulating electrode aligned in the VB. (B) Influence of stimulating electrodes on formalin induced behavioral nociception. No surgery: no surgery + formalin. Saline group: no surgery + saline. Sham surgery: bipolar electrodes implantation surgery + formalin. All data points are mean±SEM. Student’s t-test was used to compare each data point in the No surgery group with respective data points in the sham surgery group, *P<0.05. (C) Histology of the stimulation sites.
