Abstract

We describe an endocrine model of dual or multiple stochastic generators of episodic pulse signals, provide a sensitivity analysis of output responses, and illustrate the statistical effects of a plurality of independent pulse generators on peak detector performance (sensitivity, specificity, positive accuracy, and negative accuracy). We define the probability distribution of random summation or interference events and evaluate physiological implications of two or more interacting pulse-generator systems. Such observations offer a basis for quantitative examination of the operating characteristics of two or more interacting endocrine pulse generators in specified physiological contexts.
