我们成功地可视化了人体正中神经和尺神经从前臂到Erb’s点的复合神经作用磁场（CAFs）。为了观察CAFs，我们使用了一种为人类周围神经开发的超导量子干涉装置梯度测量系统。CAFs被可视化为由前后偶极子组成的四极模式。CAFs沿解剖通路传播，并在近段纵向延伸。最合理的解释是，在刺激腕部正中神经后，当前导偶极子到达近段时，后偶极子出现峰值分离。建议观察caf的时间色散。
We successfully visualized the compound nerve action magnetic fields (CAFs) in the human median and ulnar nerves from the forearm to Erb's point. To observe the CAFs, we used a superconducting quantum interference device gradiometer system that was developed for human peripheral nerves. The CAFs were visualized as a quadrupole pattern consisting of leading and trailing dipoles. The CAFs propagated along the anatomical pathway and extended longitudinally in the proximal segment. The most reasonable explanation is that the peak separation in the trailing dipole appeared when the leading dipole reached the proximal segment after stimulation of the median nerve at the wrist. A temporal dispersion of the CAFs was suggested to be visualized.
