Publisher's Synopsis
Excerpt from Memoirs on the Physiology of Nerve, of Muscle and of the Electrical Organ
Hering rejects this theory on the ground that the changes of which positive polarisation' is the expression, have their seat exclusively at the anode, and explains the experimental facts used by du Bois in proof of 'internal polarisation' (that is of a polarisation affecting all traversed structures, and consisting in the coming into existence of electromotive forces all along the line of flow, and not merely at anodes or cathodes), on the sup position that he employs structures in which, in consequence of their heterogeneity, such sudden transitions from less to greater density occur in the course of the current-paths, that the effects of anodes are produced. On the assumption that positive polari sation has its seat at the anode exclusively, he has no difficulty in referring what is observed to the well-recognised facts (1) that the effect of Opening a current led through a muscle or nerve is to produce excitation at the anode; and (2) that the characteristic expression of the excitatory state is negativity; and accordingly, while recognising the essential relation of the change in question to the functional activity of the organ in which it manifests itself, he prefers to speak of it as 'anodic after efl'ect' rather than as positive polarisation.'
