低频电刺激对人体神经系统兴奋性作用研究

Effect of low frequency electrical stimulation on human nerve excitability

电刺激在医学领域应用广泛,但其作用机理仍需要深入研究。利用电刺激器输出低频电脉冲对实验者左手拇指根部,正中神经的正上方进行刺激,并记录刺激前后脑电信号,通过对比分析刺激前后实验者脑电功率谱的变化,探讨低频电刺激对人体神经系统可能产生的兴奋性作用。

Electrical stimulation is well used in medical therapeutics, but the mechanism still needs to be studied further. This paper applies an electrical stimulator to generate low frequency pulse, which is used to stimulate at the root of the thumb, right on the median nerve. EEGs were recorded before and after the stimulation. Comparing the EEGs changes between the former and latter using power spectral analysis, the effect of low frequency electrical stimulation on human nerve excitability is discussed.
