Abstract

After a detailed introduction the problem from the literature of the evaluation of the action potential authors listed a new solution for the integration of action potentials enabling simple and rapid recording of the obtained integrated data on action potentials of the mastificatory musculature in a manner not yet described in the world dental literature. The integrator operates in such a way that the monotonously rising curve, representing the integral of the voltage is restricted to one value only. When this value is achieved the process starts anew along with emitting of an electrical impulse. For the integration of the voltage a pentode is used in the saturated region. The number o impulses in the time unit gives the value of the integral of the voltage curve under observation, in volt seconds. The accuracy achieved with this method exceeds 3 % . The authors suggests the use of this method especially for the integration of action potential sums for the skeletal musculature.
