Light-induced Desynchrony of a Multi-oscillatory Circadian System in Per2-deficient Mice
Journal of Biological Rhythms, Ahead of Print. <br/>ThePeriod (Per)gene was first identified inDrosophilaas a key regulator of circadian rhythms, with mutations that altered or abolished behavioral rhythmicity. Mammals possess 3 homologs,Per1,Per2...

Influence of Diurnal Rhythms and Aging on Pupil Size Changes During Dark Adaptation in Mice
Journal of Biological Rhythms, Ahead of Print. <br/>During dark adaptation, pupil size changes in association with visual adaptation processes; however, the influence of diurnal phase (daytime vs nighttime) and aging on these changes remains uncle...

Variations in the Timing of Bipolar Mood Cycles Associated With Interactions of the Moon’s Synodic, Tropical, and Anomalistic Cycles
Journal of Biological Rhythms, Ahead of Print. <br/>The Moon’s motion around the Earth is complex, governed by interactions among several types of cycles that arise from different aspects of its orbit. The 29.53-day synodic cycle occurs as the Moo...

A Lentiviral Fluorescent Reporter to Study Circadian Rhythms in Single Cells
Journal of Biological Rhythms, Ahead of Print. <br/>Circadian rhythms—self-sustained, ~24-h oscillations in transcript and protein levels—are generated by a cell-autonomous molecular clock. These rhythms shape how individual cells respond to exter...
