脊椎体感诱发电位的体表记录及其起源的探讨

Study of Body Surface Recording of Spinal SEP and Its Origin

本文介绍并分析了叠加平均的信号处理方法,说明了该方法能够对噪声和干扰进行抑制,并用此方法从体表记录了家兔的脊椎体感诱发电位,获得了由三个波峰组成的诱发电位信号,讨论分析了第一个波峰的起源,认为该波峰代表了脊椎的反射电活动,

In this paper the signal average processing method was used. Why this method can inhibit the noise and interference was analyzed. We success fully recorded the spinal SEP from the body surface of rabbits. The Waveform of the rabbit spinal SEO consists of three peaks. The origin of the first peak was discussed. We think that the first peak may represent the reflex electrical activities in the spinal cord.
