The High Pressure System of the Mammalian Circulation as a Dynamic Self-Organizing System

摘要: Highly stable fluctuations of arterial pressure are seen when rhythmic changes heart rate and blood (measured indirectly by the non-invasive technique photoplethysmography in earlobe made hyperemic) continuously measured during progressive relaxation healthy subjects. Associated with physical mental relaxation, aperiodic become entrained into a characteristic mode (frequency ca. 0.15Hz) 27 out 28 subjects lying comfortably. This rhythm could be clearly distinguished from respiratory sinus arrhythmia waves (ca. 0.25Hz) as well slower reflecting sympathetic activity (below 0.1Hz). rhythm, further stabilized early sleep, was regularly abolished activity, standing, exposure to various stimuli. The also known occur postganglionic muscle nerve is discussed macroscopic projection synergetic process taking place cooperative mechanical system (the Windkessel vessels) exchanging information via afferent, central efferent neuronal systems within CNS. In generalizing principle coherence mesoscopic subsystems, we postulate that many (heart, arteries types arterioles, afferent neurons, variable circuitry, interneurons neurons) get due mutual enslaving producing cooperativity. energetic informational aspects reduction cardiovascular drive (as control parameters) progressively active mechanisms (information compression) discussed. A phenomenological model for large (“WKS-CNS ensemble”) presented site generation order under conditions decreasing activity.
