摘要：

We have geometrically investigated the relationship among the state-dependent cardiovascular dynamics during physiological states such as sleep and wakefulness. Here, an impulse response analysis is carried out, in order to anatomize our geometrical results in a temporal domain. As a result the autonomic regulation is suggested ta be firmly functioning during slow wave sleep, while weakened or slightly unstabilized during rapid eye movement sleep, During wakefulness, although the state-dependent characteristics of impulse responses varied from subject to subject, the tendency held within a subject, These results are suggested to provide a microscopic interpretation for tile geometrically obtained state-dependency of cardiovascular dynamics during sleep and wakefulness.
