Abstract

Information extracted from whole-nerve electroneurograms, recorded using electrode cuffs, can provide signals to neuroprostheses. However, the amount of information that can be extracted from a single tripole is limited. This communication demonstrates how previously unavailable information about the direction of action potential propagation and velocity can be obtained using a multi-electrode cuff and that the arrangement acts as a velocity-selective filter. Results from in vitro experiments on frog nerves are presented.

摘要

从使用电极套记录的全神经电图中提取的信息可为神经假体提供信号。然而，从单个三极电极中可提取的信息量是有限的。本通讯展示了如何使用多电极套获得关于动作电位传播方向和速度的先前无法获得的信息，并且这种装置起到了速度选择滤波器的作用。文中给出了对青蛙神经进行的体外实验结果。
