Abstract
Analysis of dominant rhythms of the brain’s electrical activity and individual paired brainwave interactions provides limited information about physiological states and functions, in contrast to a more general approach that considers the coordination of all significant cortical rhythms within a complex network. This approach, without refuting traditional neurophysiological concepts, provides more comprehensive details about the coordinated dynamics of rhythmic processes, thereby improving diagnostic capabilities. Using the concept of cross-communication of physiologically significant cortical rhythms, in this study, we examine the characteristics of brainwave coordination in adolescents with traumatic brain injury (TBI) at different stages of the sleep-wake cycle. Using a simplified analysis method focusing on the behavior of average values of the relative spectral power, we note significant differences between the coordinated behavior of brain waves in adolescents with TBI and healthy individuals of the same age. These differences are observed in wakefulness and become insignificant during deep sleep, which may contribute to the therapeutic effect of sleep in traumatic brain injuries.
