Abstract :
In order to study autonomic nervous system during sleep, body motion wave, BMW, was adopted. BMW was produced by dynamic air pressure sensor to obtain information of respiration, pulse and body action during sleep, viz., unconscious state. In addition, the information of body position produced by a pressure sensor array was adopted. As a result, it was demonstrated that (1) the rate pattern were classified into almost three patterns, (2) the transition of rates of respiration and pulse had periodicity, and (3) the periods in the transition of the rates of respiration and pulse did not always agree, (4) the rate of action changed through one night in the range approximately one or two times for every minute. It was thus found that both respiratory and circulation systems were controlled by autonomic nervous system with a little different manner. In addition, body actions produced by skeletal muscles controlled by somatic nervous system, occurred approximately with some rhythms during sleep, as well known to be sleeping posture.
