Abstract

A noninvasive biomagnetic sensor system that uses magnetic toroids for both neural stimulation and detection is described. It is shown that analytical signals obtained by direct magnetic detection (no signal averaging) compare favorably with electrical monitoring and that dose-response curves for local anesthetics correlate well between the two methods. Neural lifetimes are significantly extended when the noninvasive biomagnetic sensing system is used.

摘要

描述了一种使用磁环进行神经刺激和检测的非侵入性生物磁传感器系统。结果表明，通过直接磁检测（无需信号平均）获得的分析信号与电监测相比具有优势，并且两种方法之间局部麻醉剂的剂量-反应曲线相关性良好。当使用非侵入性生物磁传感系统时，神经寿命会显著延长。
