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

Figure 2

EA reduced the excitatory effects of brief sciatic nerve stimulation on the firing rate of PENs and had a similar reducing effect on PINs in CCI rats. (a) Example of EA reducing the effects of acute noxious stimulation on discharges of hippocampal PENs in CCI rats. (b) Example of EA regulating the effects of acute noxious stimulation on discharges of hippocampal PINs in CCI rats. (c) EA reduced the effects of acute noxious stimulation on the firing rates of hippocampal PENs () at different times after the noxious stimuli in CCI rats. (d) EA reduced the effects of acute noxious stimulation on the firing rates of hippocampal PINs () at different times after the noxious stimuli in CCI rats. B on the -axis stands for the background firing rate before the noxious stimulus. : compared with the CCI group, .
