Age-related aspects in coordination among brain rhythms during sleep-wake cycles

Abstract

Cooperative dynamics of complex networks is one of the promising interdisciplinary research areas, which includes various fundamental and applied fields. For many objects of the surrounding world, the network approach is the most suitable paradigm, allowing us to study their functioning taking into account the topology of links of individual elements. With the advent of network physiology, it became possible to look at the dynamics of brain waves from a different point of view. Recently, a new paradigm of network interactions of physiologically significant cortical rhythms has been presented and various classes of coupling forms have been established that exist in a certain physiological state and change with the state of the organism.

This study aims to discuss an issue that has remained outside the scope of previous works, namely, age-related features of cooperative dynamics of brain waves. We propose a simple approach to the analysis of the coordination of brain rhythms during transitions between functional states and discuss the possibilities of such approach using the example of different stages of sleep-wake cycles in three age groups. During light and deep sleep stages, an increase in the degree of correlation with age for a different set of rhythm pairs is noted. The most pronounced changes are demonstrated in the REM sleep stage.
