Stimulation of the uninjured end, approximating it to the condition of the injured, might then be said to induce a cuproid change.
Response in the Living and Non-Living Jagadis Chandra Bose 1897
-
The electric change produced in a normal nerve by stimulation may therefore be expressed by saying that there has been a negative variation, or that there was a current of action from the more excited to the less excited, or that stimulation has produced a cuproid change.
Response in the Living and Non-Living Jagadis Chandra Bose 1897
-
The uninjured end is therefore comparable to the zinc in a voltaic cell (is zincoid), the injured being copper-like or cuproid. [
