Optical rotation signal of nerve and the Faraday effect.
The polarity of the optical rotation signal, recorded from the lobster nerve, was reversed when the direction of incident light was changed by 180 degrees. This is a property of the Faraday rotation, but the magnetic field by the action current was too small to explain the size of the observed signal.
