Influence of contralateral S2 stimulation on ongoing and heat-evoked discharge of spinal wide dynamic range neurons in the spinal dorsal horn of hypersensitive neuropathic animals. A: ongoing discharge rate. B: heat-evoked discharge rate. C: latency of the heat-evoked discharge. D: duration of the heat-evoked discharge. Pre = before S2 stimulation, Real S2 = during S2 stimulation at the intensity of 30 µA, Fake S2 = during S2 stimulation at the intensity of 0 µA. Error bars represent SD (nRealS2 = 9, nFakeS2 = 7), *P < 0.05 (Bonferroni-corrected t-test).
