A recent study found a link between the formation of sleep-related brain activity patterns and memory reactivation during sleep. Researchers from LMU's Department of Psychology, Max Planck Institute for Human Development, and University of Oxford reanalyzed the data to identify respiration as a potential central pacemaker. The precision of coupling sleep-related brain rhythms increases in adolescence and declines in old age. The study also revealed a connection between respiration, slow oscillations, and sleep spindles. Further investigations will explore the relationship between sleep disorders, respiratory disorders, declining memory function, and potential interventions like CPAP masks.
