The most essential element in the reactionof degeneration is the modal change,—the slowly appearing muscularresponse,—so at variance with the instantaneous eifect produced in in importance is the lessened faradic control of the muscle, and, last,the polar modifications. The variations in the galvanic and faradicresponses in disease are due principally to the fact that currents of acertain strength and duration are required to actuate the changed sarcodecells, and the rapidly interrupted faradic current thereby becomesinoperative. The galvanic current, if interrupted with sufficient rapid-ity, is equally powerless. In some conditions is found a simple increase or decrease of electricalexcitability, constituting a pure quantitative change.
