Under certain conditions nerves (such as the frog sciatic) exhibit electron spin resonance signals with several unusual properties: (i) variable g value and linewidth, (ii) anisotropic g tensor, and (iii) g value dependence on temperature. Such a signal must be due to a small ferromagnetic crystal formed when the nerve is subjected to pressure, such as that due to mechanical injury.
在某些条件下，神经（如青蛙坐骨神经）会表现出具有几种异常特性的电子自旋共振信号：（i）g值和线宽可变，（ii）g张量各向异性，以及（iii）g值对温度的依赖性。这样的信号必定归因于神经受到压力（如机械损伤所致压力）时形成的小铁磁晶体。
