The dynamical premise for desynchrony between circadian rhythm and the sleep-wake cycle

摘要

Most of human endogenous processes are subject to the circadian rhythm. This rhythm, in turn, demonstrates the adaptation of the body to the cycle of day and night, that is, it is regulated by illumination. Normally, the sleep / wake cycle is synchronized with the circadian rhythm, but sometimes, for various reasons, the phenomenon of desynchronization occurs, which can take a different form. We present a model study of such a phenomenon by introducing both random and periodic forcing on the neuronal nuclei responsible for sleep and wakefulness. The results of the study confirmed the experimental data on changes in sleep patterns, and also made it possible to predict that the effect on the homeostatic process associated with the sleep / wake cycle may lead to desynchronization.
