Figure 3.

Mean data showing the baseline discharge of group III and IV afferents in sham and CHF rats (A) and the responses of group III and IV afferents to static contraction induced by electrical stimulation of L5 ventral root in sham and CHF rats (B). Mean data showing the discharge of group III and IV afferents in response to two levels of passive stretch (C) and two doses of capsaicin (D) respectively in sham and CHF rats. Data are expressed as Mean ± SE. ^*P < 0.05 vs. sham, ^†P < 0.05 vs. lower level of stretch or lower dose of capsaicin. [Reprinted from Wang et al. (2010a).
