Peripheral NMDA Receptors Mediate Antidromic Nerve Stimulation-Induced Tactile Hypersensitivity in the Rat

Figure 2

Tactile hypersensitivity following tetanic ES of the decentralized L5 SN. A tetanic ES of the L5 SN (L5 SN-ES) in rats with L5 DR induced a significant decrease in PWTs in the affected hind-paws on days 1 through 7 after ES compared with the baseline, contralateral hind-paws, and sham-operated animals. The abbreviations B and D denote the baseline before DR and postoperative days after DR, respectively. The figures in parentheses indicate the number of animals used. The error bars represent the SEM. versus sham animals. ^# versus baseline. ^## versus contralateral hind-paws.
