Travelling waves in children: sex and age influences on sleep physiology and cognition

Brain maturation and sleep patterns evolve throughout childhood, intricately influencing memory consolidation, emotional regulation, and vigilance. However, it remains unclear whether changes in sleep and cognitive functions follow similar or distinct developmental trajectories as a function of age and sex during childhood. In this study, we included 61 healthy school-aged children, aged 5 to 12 years old, and administered several cognitive tasks before and after they spent one night under polysomnography at home. The main goals were to investigate how age and sex influenced sleep physiology and the link between sleep and cognition in this population. Interesting results have been found and are currently described in a paper which is in preparation.
