Representative recordings showing the discharge of group III (A–D) and IV (E–H) afferents in response to static contraction induced by electrical stimulation of L5 ventral root in sham (Group III in panel (A): CV, 5.2 m/s; Group IV in panel (E): CV, 0.8 m/s) and CHF rats (Group III in panel (B): CV, 7.0 m/s; Group IV in panel (F): CV, 0.5 m/s). (C) and (D), 5-s recording of two group III fibers discharge derived from the broken-lined box in (A) and (B), respectively. (G) and (H), 6-s recording of two group IV fibers discharge derived from the broken-lined box in (E) and (F), respectively. [Reprinted from Wang et al. (2010a).
