title: Measuring the stimulating energy threshold in living tissues.
abstract: The paper summarizes the various methods of measuring the stimulation threshold in living tissues and emphasizes the usefulness of energy measures. An analog instrument for the direct measurement of the energy threshold is proposed and some experimental results obtained by its clinical application are reported.
