Pressor effect of the baroreceptor reflex, depressor effect of septal stimulation and their interactions.

Experiments on limbic modulation of the baroreceptor system show that changes in blood pressure caused by electrical stimulation of the septal area (PRS), carotid occlusion (PRC) and the interaction of these factors (PRI) can be described by power functions, if the pressure curves are divided into two branches, taking into account the minimum pressure attained during PRS and the time of occlusion release during PRC and PRI. A system analysis approach may be an important tool to disclose characteristics of changes undergone by blood pressure, which remain otherwise undetected.
