[Comparative study of nerve stimulation factors by a single rectangular impulse and a series of rectangular impulses]

The experiments were performed on the sciatic nerve of Rana temporaria. A single rectangular electric impulse and a series of rectangular microsecond impulses were used for stimulation. The threshold amplitude of a single impulse and the average voltage in series of impulses were compared. It was experimentally shown that application of a series of impulses as a stimulus necessitated less values of stimulation near the threshold. There was no significant difference between the average voltage in a series of impulses and the amplitude of a single rectangular impulse in stimulation far up the threshold.
