| 摘 要： | 本文提出了一种分析神经干复合动作电位的方法。这种方法通过对复合动作电位进行两维谱分析:时域FFT谱分析和空域的Prony谱估计,从而确定神经干中各类纤维的传导速度,并估计具有不同传导速度的动作电位波形。仿真实验和动物实验给出了较为满意的结果。

| Abstract: |
A spectrum estimation method was presented for studying propage
tion velocities of nerve activity by compound action potential analysis.
This method was based on two-dimensional spectrum analysis FFT for
temporal frequencies and Prony method for spatial frequencies,and con-
sists of two parts: 1. determining the propagation velocities of differ-
ent fibers in a nerve trunk, and 2. estimating the action potential wavc-
shapes of different velocities. The rcsults of simulations and animal ex-
permints were satisfactory. |
