Concerning reflex summation.

Abstract

A simple, linear, noninteractive model of the reflex control of blood pressure was developed to demonstrate that simple linear addition of the responses of the baroreceptor reflexes can produce observations that appear to have resulted from a redundant control system. Our analysis indicated that common experimental paradigms such as hemorrhage with sequential reflex ablation, which are often used to evaluate reflex interactions, can be simply interpreted. Complex nonlinear interactions need not be postulated to explain data that appear to indicate a redundant control system.
