Electroacupuncture Reduces the Effects of Acute Noxious Stimulation on the Electrical Activity of Pain-Related Neurons in the Hippocampus of Control and Neuropathic Pain Rats
The differences in effects of acute noxious stimulation on the firing rate between sham and CCI rats. The brief sciatic nerve stimulation had a greater excitatory effect on the firing rate of PENs in CCI compared to sham rats (a) and a similar effect on PINs in both CCI and sham rats (b). Also, EA blocked the excitatory effect of the acute noxious stimulus on the firing rate of PENs in both sham and CCI rats (c) and produced slightly less blocking of the inhibitory effect of noxious stimulation on PINs in CCI rats compared to sham rats (d). : compared with the control group, .
