Humans 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 ganglion cells maximally sensitive to blue light.
A 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.
Circadian 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.
The effects of sleep loss on cognitive and behavioral ...
Secondary 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 appropriate time-dependent changes in blood pressure.
Normally occurring developmental changes in adolescents are associated ...
Biological rhythms are controlled by a master central circadian clock located in a pair of nuclei in the brain called the suprachiasmatic nucleus (SCN).
Circadian rhythm disorders occur when a mismatch exists between the internal biological clock and ...
Alternating 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.
Extrinsic circadian rhythm disorders occur when an individual alters the timing of sleep relative to their internal biological rhythm (circadian clock).
