用电生理实验方法研究针刺镇痛原理时,中枢神经细胞放电频率数是一主要指标。在电针刺激过程中,电针刺激信号伪迹与细胞放电信号同时被引入记录装置,记录得出的频率数,实为两者信号的综合,导致记录失真。致使有些工作者在电针时,停止记录,因而不能观察在电针过程中细胞放电的变化。为此,设计了一种简易的去电针伪迹装置。近几年来,经我室神经生理实验组的应用,获得满意的结果。
Electrophysiological experimental study of acupuncture analgesic principle, the number of central nervous cell discharge frequency is a major indicator. Electroacupuncture stimulation in the process, the electro-acupuncture stimulation signal and cell discharge signal is also introduced into the recording device, the number of records of the frequency, in fact, a combination of the two signals, leading to record distortion. As a result, some workers stop recording during the electroacupuncture and can not observe the changes in cell discharge during electroacupuncture. For this reason, a simple de-electro-pin device has been designed. In recent years, our laboratory application of neurophysiological results obtained satisfactory results.
