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 1

EA reduced the excitatory and inhibitory effects of brief sciatic nerve stimulation on the firing rates of PENs and PINs, respectively, in sham rats. (a) Example of EA reducing the effects of acute noxious stimulation on discharges of hippocampal PENs in the sham group. (b) Example of EA reducing the effects of acute noxious stimulation on discharges of hippocampal PINs in the sham group. (c) EA reduced the effects of acute noxious stimulation on the firing rates of hippocampal PENs () at different times after the noxious stimuli in sham 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 sham rats. The 10-second stimulation of the sciatic nerve occurred immediately before 0 min, not at 0 min. B on the -axis stands for the background firing rate before the noxious stimulus. : compared with the control group, .
