✦ Synopsis

It is one of the conveiitioiis of nerve and muscle physiology, recently supported by the experiments of Furusawa ( '29), that the action potential consists of a negative variation of the demarcation potential; and the inference is usually drawn that they are reciprocal functions of the same fundamental process, the action potential consisting of a transitory abolition of the nerve's potential of polarization. With the further assumption often made, that depolarization, whether as action or demarcation potential, involves a change in permeability of the nerve membrane, this discussion is not materially concerned.
