To understand regulatory mechanisms of the cardiovascular system from an integrative point of view based on its state-dependent dynamics, mutual relationships among multivariate dynamics in slow-wave sleep (SWS), rapid-eye-movement sleep (REM), supine posture (SUP), and standing posture (STD) were investigated. Kullback-Leibler divergence (KLD) is used to quantify the mutual relationship between the state-specific dynamics. The relationship between the multivariate dynamics is represented by KLDs between the dynamics of the same signals in the different states and those between the dynamics of the different signals in the same state.
