A two-oscillator SCN model with period adaptation and systemic feedback captures photoperiod and T-cycle aftereffects in vivo and in explants

A multistable slow-fast model of affective state switching under circadian drive

This paper introduces a slow-fast model of affective dynamics to study how circadian rhythms and perturbations influence transitions between physiological and pathological mood states in bipolar disorder.

Chronotype asymmetry arises from stochastic sleep homeostasis under circadian entrainment

This study shows that chronotype skew arises from stochastic sleep homeostasis interacting with circadian rhythms, not directly from circadian period distribution.

Differential Effects of Sex and Age on Daily and Infradian Rhythms of Mice Running Title: Sex and Age Differences in Mouse Rhythms

This study examines how sex and age affect circadian and infradian rhythms in mice, finding sex- and age-specific differences in activity patterns and physiological responses to isolation.

The earliest circadian clock in the mammalian brain emerges in the embryonic choroid plexus

The paper identifies the embryonic choroid plexus as the earliest circadian oscillator in the mammalian brain, showing bifurcation dynamics that couple to maternal rhythms.

Intrinsic circadian timekeeping properties of the thalamic lateral geniculate nucleus

This study identifies autonomous circadian timekeeping mechanisms in the lateral geniculate nucleus (LGN) of the thalamus, showing intrinsic clock gene expression and light-entrainable oscillations in specific subregions.

Daily orexinergic modulation of the rat superficial layers of the superior colliculus - implications for intrinsic clock activities in the visual system

The paper investigates daily orexinergic modulation of the rat superior colliculus, showing circadian coordination between orexin input and visual system activity.

Weak Coupling Between Intracellular Feedback Loops Explains Dissociation of Clock Gene Dynamics

The paper shows that weak coupling between feedback loops in circadian clocks leads to dissociated gene expression dynamics at the single-cell level.
