Abstract

Introduced about two decades ago, vagus nerve stimulation (VNS) therapy has been increasingly used for the treatment of refractory epilepsy recently. This study was set out to compare the effects between VNS and electroacupuncture (EA) on pentylenetetrazole (PTZ) induced epileptiform activities in the rat cerebral cortex. Under general anesthesia, the parietal cortex of the rat (n = 20) was exposed to record the cortical epileptiform activities. The left vagus nerve was stimulated at 30 Hz, 1 mA or 3 mA for 5 min. For EA, "Dazhui" acupoint (GV14) was stimulated with a pair of acupuncture needles with the same parameters. The results show that both VNS and EA at either 1 mA or 3 mA could inhibit the PTZ-induced cortical epileptiform activities, and higher stimulation (3 mA) was not associated with a greater inhibition. In the cases that showed inhibitory responses, there were no statistically significant differences between the two modalities, implying that EA could be comparable to VNS in the treatment of epilepsy. Thus, under current experimental settings, the antiepileptic effect induced by electrical stimulation appeared not vagal specific, and EA could be a good alternative to VNS in the management of epilepsy.
