The first detection of the magnetic field of a stimulated peripheral nerve in man is presented. The measurement was performed noninvasively and in vivo on a healthy subject. The spatio-temporal field distribution is utilized to calculate the location of bioelectric activity on the basis of the equivalent current dipole model. The localization of the active nerve tissue is confirmed by a computer tomography image of the upper arm cross-section. Furthermore, a calculation of the total current distribution in the nerve explains the observed morphology of the signal.
本文展示了人类受刺激外周神经磁场的首次检测。该测量在一名健康受试者身上进行,采用非侵入性活体测量。利用时空场分布,基于等效电流偶极子模型计算生物电活动的位置。通过上臂横截面的计算机断层扫描图像确认了活跃神经组织的定位。此外,对神经中总电流分布的计算解释了所观察到的信号形态。
