首次检测到的磁场刺激周围神经在人。测量是在健康受试者体内非侵入性进行的。在等效电流偶极子模型的基础上，利用时空场分布计算生物电活动的位置。活动神经组织的定位通过上臂横截面的计算机断层扫描图像来确认。此外，神经中的总电流分布的计算解释了所观察到的信号形态。
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.
