This study investigates the effects of natural daylight and physical activity on circadian phase using a Bayesian crossover experiment, finding inconclusive results.

This study examines how fetal activity patterns in utero relate to postnatal infant sleep behavior, finding that fetal circadian entrainment predicts infant sleep preferences.

This study examines how habitual light exposure-related behaviors affect sleep timing and complaints in a large international sample, finding that outdoor time and device use in bed have significant impacts.

The study finds no seasonal variation in fatigue, sleepiness, or insomnia symptoms, suggesting spring fatigue is a cultural phenomenon rather than a biological syndrome.

The paper analyzes prediction error processing during sleep using information-theoretic methods, finding reduced and redundant neural information with deeper sleep and REM.

The paper examines cardiac responses to auditory irregularities during sleep, showing slowed cardiac activity to global deviants in REM sleep and cardiac acceleration in light NREM sleep, indicating hierarchical information processing variations.

This study investigates the impact of blue-yellow light changes on the human circadian clock and sleep, finding no significant effects under moderate light levels.

The paper develops a consensus checklist and guidelines for reporting non-visual light effects in human studies, resulting in a 25-item checklist after expert feedback.

This study investigates whether high-melanopic light affects sleep and vigilance, finding no differential effects despite melatonin suppression.

This study investigates how the sleeping brain responds to familiar and unfamiliar voices, finding that unfamiliar voices elicit stronger neural responses, particularly through K-complexes and oscillatory activity.

This study assesses whether circadian rhythms in brain-injured patients can be accurately measured using actigraphy after correcting for passive movements.

The paper evaluates how environmental stimuli are processed during different sleep stages, finding that voice familiarity assessment continues during sleep and that sleep spindles and slow oscillations modulate stimulus processing based on salience.
