Light as a Modulator of Cognitive Brain Function.
Gilles Vandewalle, PhDHumans are a diurnal species usually exposed to light while engaged in cognitive tasks. Light not only guides performance on these tasks through vision but also exerts non-visual effects that are mediated in part by recently discovered retinal...

Chronic stimulation of the vpac2 receptor in-vivo lengthens circadian period
Harry Pantazopoulos, PhDA number of studies have found that people with depression or bipolar disorder have abnormal circadian rhythms, illustrating a relationship between the sleep/wake cycle and mood.

Controlled patterns of daytime light exposure improve circadian adjustment in simulated night work.
Marie Dumont, PhDCircadian misalignment between the endogenous circadian signal and the imposed rest-activity cycle is one of the main sources of sleep and health troubles in night shift workers.

Per2 Rhythms Within and Beyond the Suprachiasmatic Nucleus of Pregnant & Diestrous Rats (Rattus norvegicus)
Jessica Schrader, BSSecondary pacemakers throughout the brain and body are dependent on the primary pacemaker in the suprachiasmatic nucleus (SCN) for information about the circadian cycle to ensure, for example, hormone secretion at the correct time or...

Circadian rhythm perturbation leads to reorganization of suprachiasmatic nucleus network
Lily Yan, PhDBiological rhythms are controlled by a master central circadian clock located in a pair of nuclei in the brain called the suprachiasmatic nucleus (SCN).

Sleep Schedules in Patients With Circadian Rhythm Disorders
Richard D. Simon Jr, MDCircadian rhythm disorders occur when a mismatch exists between the internal biological clock and ...

Regulation of Photic Signaling Peptides in the Mammalian SCN Circadian Clock: In Vivo Measurements of VIP and GRP
Jessica M. Francl, MSAlternating daylight with nighttime darkness influences the circadian rhythm signals generated by the suprachiasmatic nucleus (SCN), a region in the hypothalamus that controls other biological clocks in the body.

Shift Work Effects on Sleep and Performance
Paul Knoepflmacher, MDExtrinsic circadian rhythm disorders occur when an individual alters the timing of sleep relative to their internal biological rhythm (circadian clock).
