Using 'classical' experimental protocols, a human phase-response curve (PRC) to a single 3-h bright light pulse has been established. When the light pulse was centred slightly before the time of body temperature minimum, the circadian system delayed, whilst a pulse slightly after the minimum advanced it. Maximum phase shifts were about 2 h. When light pulses over 3 successive cycles were used, larger shifts (4-7 h) were produced. It is concluded that the human PRC does not differ in principle… Expand

The Effect of Multiple Pulses of Light on the Circadian Phase Response of the Rat
TLDR
These results suggest the underlying pacemaker to be nonsimple, and results with a second, third, or fourth light exposure were not fully predictable from a phase response curve derived from a single light pulse. Expand
A Phase Response Curve to Single Bright Light Pulses in Human Subjects
TLDR
These data provide a comprehensive characterization of the human phase response curves (PRCs) to single bright light exposures under highly controlled laboratory conditions. Expand
Human phase response curve to a single 6.5 h pulse of short‐wavelength light
TLDR
It is suggested that short‐wavelength visible light exposures may be more efficient than traditional high‐intensity white light exposures for treatment of circadian rhythm sleep disorders. Expand
Human phase response curve to a 1 h pulse of bright white light
TLDR
It is demonstrated that the circadian pacemaker is sensitive to short‐duration light pulses with a non‐linear relationship between light duration and the amount of resetting, as well as the magnitude and direction of the resetting response of the pacemaker to light. Expand
Demonstration of rapid light-induced advances and delays of the human circadian clock using hormonal phase markers.
TLDR
The immediate response of the human circadian clock to a single 3-h light pulse is thus characteristic of "type 1" resetting. Expand
The human phase response curve (PRC) to melatonin is about 12 hours out of phase with the PRC to light.
TLDR
The human phase response curve (PRC) to melatonin appears to be about 12h out of phase with the PRC to light, which suggests that a function for endogenous melatonin is to augment entrainment of the circadian pacemaker by the light-dark cycle. Expand
Light of domestic intensity produces phase shifts of the circadian oscillator in humans
TLDR
A detailed examination of the phase shifts from one day to the next showed that small advances and delays were superimposed upon this drift, which depended upon the time of exposure to lighting relative to the temperature minimum, as would be predicted from a phase-response curve. Expand
Human circadian pacemaker is sensitive to light throughout subjective day without evidence of transients.
TLDR
It is found that bright light induces phase shifts throughout subjective day with no apparent dead zone, and there is no evidence of transients in constant routine assessments of the fitted temperature minimum 1-2 days after completion of the resetting stimulus. Expand
Human responses to bright light of different durations
TLDR
Shorter light exposures more efficiently phase‐shift the clock, suppress melatonin and induce alertness, according to the effects of different durations of exposure to a single high‐intensity light pulse. Expand
Human phase response curve to intermittent blue light using a commercially available device
TLDR
It is shown for the first time that a small, commercially available, portable blue light device is capable of shifting the clock when it is administered daily over a 2 h window (90 min blue light as 30 min pulses with 15 min breaks). Expand

Bright light induction of strong (type 0) resetting of the human circadian pacemaker.
TLDR
The data indicate that the sensitivity of the human circadian pacemaker to light is far greater than previously recognized and have important implications for the therapeutic use of light in the management of disorders of circadian regulation. Expand
Adaptation to abrupt time shifts of the oscillator(s) controlling human circadian rhythms.
TLDR
After an eastward shift the phase of the rhythms appeared to shift in the appropriate direction when studied under nychthemeral conditions whereas the endogenous oscillator either showed no consistent behaviour or, in the control of urate excretion, ashift in the wrong direction. Expand
Phase-shifting effects of bright morning light as treatment for delayed sleep phase syndrome.
TLDR
It is found that 2 h of bright light exposure in the morning together with light restriction in the evening successfully phase advanced circadian rhythms of core body temperature and multiple sleep latencies in patients with delayed sleep phase syndrome. Expand
Reduction of human sleep duration after bright light exposure in the morning
TLDR
In 8 subjects the spontaneous termination of sleep was determined after repetitive exposure to either bright or dim light, between 6.00 and 9.00 h, on 3 days preceding sleep assessment, which can be interpreted as a direct effect of light on the circadian phase of the wake up threshold. Expand
Bright light resets the human circadian pacemaker independent of the timing of the sleep-wake cycle.
TLDR
Exposure to bright light can indeed reset the human circadian pacemaker, which controls daily variations in physiologic, behavioral, and cognitive function, as indicated by recordings of body temperature and cortisol secretion. Expand
Light-induced suppression of endogenous circadian amplitude in humans
TLDR
It is reported that exposure of humans to fewer cycles of bright light, centred around the time at which the human circadian pacemaker is most sensitive to light-induced phase shifts, can markedly attenuate endogenous circadian amplitude. Expand
"Demasking" the Temperature Rhythm after Simulated Time Zone Transitions
TLDR
The two-component cross-correlation methods can be used to estimate shifts of the endogenous component of a circadian rhythm in the presence of masking factors and are therefore an alternative to constant routines when these latter are impracticable to carry out. Expand
Daily light sensitivity rhythm in a rodent.
TLDR
A daily rhythm of sensitivity to these standard light periods was found in flying squirrels otherwise maintained in constant darkness. Expand
Exposure to bright light and darkness to treat physiologic maladaptation to night work.
TLDR
It is concluded that maladaptation of the human circadian system to night work, with its associated decline in alertness, performance, and quality of daytime sleep, can be treated effectively with scheduled exposure to bright light at night and darkness during the day. Expand

TLDR
The typical student experiences the power of these circadian oscillations when staying up all night studying for an exam, and later in the morning, she or he will become more alert and start to feel better, despite the further accumulation of sleep deprivation. Expand
