Abstract

Dynamic components of central nervous, cardio-vascular and respiratory systems in the conditions of present functional state of the body were evaluated on the basis of analysis of these system parameters registered simultaneously in the real­time regime. Power distributions of amplitude fluctuations of alpha-activity, cardio-intervals and respiratory periods were analyzed. It was shown that all the subjects in all the power distributions have periodical fluctuations in all three frequency ranges described for cardiac rhythm variability (CRV). The studied spectrums have different structure. In power distribu­tions of amplitude fluctuations of alpha-activity, slow and very slow waves are prevailing and fast waves constitute only 10%. In the spectrum of cardiac rhythm variability, fast and slow waves take half of all the power distributions, while another half is taken by very slow waves. In the spectrum of respiration rhythm, fast waves prevail (more than 60 %), along with this there are very slow waves (30%) and slow waves which take just 10%.

Keywords: 14C-ethanol, absorption, concentration gradient, reabsorption
