Abstract
The rhythmically recurring spike potentials emitted by Petromyzon marinus are synchronous with the external respiratory movements but are not emitted through the branchial pores. Only total electrical shielding of the probranchial body eliminates these potentials from the water surrounding the animal. The principal area of emission is located in the eye region immediately cephalad of the first pair of branchial pores, in the area overlying the junction of the probranchial muscle and the hypobranchial branch of the parietalis. Probing of the skin with electrodes shows potentials of 1 millivolt on the surface of this area. These potentials are more than tenfold those recorded on any other part of the skin. It is assumed that the spike potentials described previously are emitted from the area defined above.This publication has 1 reference indexed in Scilit:
