CARDIAC-RHYTHM AS AN INDICATOR OF NORMAL AND PATHOLOGICAL ADAPTATION TO MENTAL EFFORT

Devotes research to the psychophysiological study of mechanisms of the functional state regulation in children with minimal mental dysfuncti ons and a control group of normal children. Interprets the data with t he help of a cybernetic model developed by R.M. Baevsky. Opines that t he changes in heart rate indicate changes in the central nervous syste m directed to the adaptation of an organism to fulfilment of offered m ental tasks. Offers a hypothesis of inadequate regulation of functiona l state in the children with minimal mental dysfunction based on the s tudy of the maturation of the heart rate control system and ontogeneti c development of attention and time perception functions.
