Morningness is associated with lower sleep spindle amplitudes and intensities during adolescence

Introduction: Circadian preference, reflected in the circadian timing of sleep onset and awakening times, and nighttime sleep spindle characteristics show marked variation between individuals, but are fairly consistent biological features during adulthood. These both have been associated with similar behavioral phenotypes related to cognitive function and mental health. However, there are no previous explorative studies on whether spindle characteristics would differ by circadian preference.
