… From this it has been supposed that such a current was not the current of injury at all, but something of an unknown nature, essentially different. The consequent perplexity is the result of a failure to understand on the one hand that there is no such thing as …

… the so-called ‘current of injury’ is, in fact, an after-effect of excitation. In the case under consideration, the section, acting as an intense stimulus, simply induces greater excita- tory reaction of the more excitable, which in this case happens, as we should have expected, to be …

… If such a convention be adopted, no confusion can arise, even when, as in the given cases, the currents of injury undergo a change of direction. Normal response positive —The normal effect of light on the retina, as noticed by all the observers already mentioned, is a positive …

… by the injury of either point of galvanometric contact ; and that, under these circumstances, the response is a negative variation of the current of injury. This experiment is | important as giving a theoretical insight into the so-called response by negative variation. It also shows how limited is …

… This will explain the reason why the action-current causes a diminution or negative variation of the current of injury, so called. One method of doing this is to cause injury to one of the two points. If this be such as to kill the tissue, then its …

found that the so-called ‘current of injury’ had in this case, owing to some hitherto unknown cause, undergone a reversal, and was now from the living to the dead, the latter being galvanometrically positive to the former, to the extent of ‘08 volt. The abnormality of the …

… This is shown by the conditions under which the so-called currents of injury arise. Mechanical or other injury and the application of cytolytic substances, which demonstrably increase permeability, always lower the potential; i.e., the altered region becomes negative relatively to unaltered regions. This effect is often …

… With regard to the so-called Current of Injury it. was shown that this arises as the after-effect of strong stimulus. It should be remembered that a cut, or the application of a heated wire, constituting mechanical and thermal sections respectively, will act as a strong stimulus …

… I have, for example, obtained such response from the roots, stems, and leaves of, among others, horse-chestnut, vine, white lily, rhubarb, and horse-radish. . ‘The “current of injury” is, generally speaking, from the injured to the uninjured part. A “negative variation ” is also produced. | obtained both the …
