How an Ultradian Light Cycle Alters Behavior and Mood

Explore how an ultradian 3.5-hour light/3.5-hour dark cycle (T7 cycle) influences cognition and mood in mice in the study titled “Delaying circadian sleep phase under ultradian light cycle causes time-of-day-dependent alteration of cognition and mood.” This research challenges the belief that direct negative effects of irregular light exposure affect behavior and introduces a fresh perspective. By examining the impact of the T7 cycle on general activity, sleep rhythms, and behavioral responses at different times of day, the study uncovers a fascinating relationship between light exposure, circadian rhythms, and behavior, revealing time-specific changes in behavior.
