Abstract
We found a chaotic pulsation in a finger's capillary vessels in both normal subjects and psychiatric patients, as well as a cardiac chaos. A proof of chaos was made by the reconstruction of dynamics in phase space and the calculation of the Lyapunov exponents. From the aspect of chaotic information processing we give a measure of the information storage capacity of observed chaos. We also found a difference in the topology of capillary and cardiac chaos, and a difference in their dependence on the subject's conditions.
