Action of the Hypothalamus

Abstract

EXPERIMENTS with an analogue model of the heart, demonstrated by me1, show that a pulse may arise, in a fluid-filled elastic system, in either of two ways : in the first, energy is cycled into the system from a mechanical source, corresponding to the physico-chemical contraction of the ventricles ; in the second, pulsation can be derived from the static head of pressure with the aid of a length of elastic tubing arranged as a wave guide. The latter device, termed an ‘oscillator’, may be employed to time delivery of energy from the external source, in such a manner that the system is self-oscillating and that the two pulses, of differing origin, are synchronous.
