The effect of frequency of stimulation on the heat production of frog's nerve

Abstract

The relation in frog''s medullated nerve between heat production and frequency of stimulation is not simple. In general it is as described in previous papers, but it depends also upon the duration of the stimulus. With a short stimulus a given increase of frequency has a greater relative effect on the heat than with a long stimulus. A nerve behaves as though it were slowed in its time relations by activity.
