Abstract
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.
