[Detection of longitudinal electric currents in frog nerves]

The data on transversal potential difference (V-x) in the sciatic nerve of a frog under the influence of the magnetic field are presented. The amplitude of the registered signal has a linear rise with an increase of the magnetic field tension. (H), while a change of (H) direction leads to a change of polarity of the signal (V-x). The presence of (V-x) is connected with the existence of the longitudinal directed stream of the light charged particles in the nerve.
