两种光学技术-光散射和双折射-已被用来检测伴随着两种类型的无髓鞘神经纤维的动作电位的快速结构变化。光散射的变化源于至少两种不同的现象，而大部分的双折射变化似乎直接取决于轴突膜上的电势差，并出现在与膜相关的径向取向的分子中。
Two optical techniques—light scattering and birefringence—have been used to detect rapid structural changes accompanying the action potentials in two types of non-myelinated nerve fibre. Changes in light scattering originate from at least two different phenomena, while a large part of the birefringence change seems to be directly dependent on the potential difference across the axon membrane, and arises in radially oriented molecules associated with the membrane.
