Short-wavelength enrichment of polychromatic light enhances human melatonin suppression potency. [PDF]
, 2015 The basic goal of this research is to determine the best combination of light wavelengths for use as a lighting countermeasure for circadian and sleep disruption during space exploration, as well as for individuals living on Earth.

Safe and Truly Ecofriendly LED Lighting
Energy Science &Engineering, Volume 13, Issue 11, Page 5068-5074, November 2025.ABSTRACT Truly ecofriendly and safe light‐emitting diode (LED) lighting in the built and urban environments requires the use of LED lights emitting significantly lower amount of blue light than conventional, first‐generation white LED lights. Thanks to substantial technology progress in the design and manufacturing of LEDs, this is now possible at the ...

Scientific Reports, 2017 In the vertebrate retina, dopamine is synthesized and released by a specialized type of amacrine cell, the dopaminergic amacrine cell (DAC). DAC activity is stimulated by rods, cones, and melanopsin-expressing intrinsically photosensitive retinal ...

Daily rhythm of melanopsin-expressing cells in the mouse retina
Frontiers in Cellular Neuroscience, 2009 In addition to some other functions, melanopsin-expressing retinal ganglion cells (RGCs) constitute the principal mediators of the circadian photoentrainment, a process by which the suprachiasmatic nucleus (the central clock of mammals), adjusts daily to

Melanopsin-Driven Light Adaptation in Mouse Vision [PDF]
Current Biology, 2014 In bright light, mammals use a distinct photopigment (melanopsin) to measure irradiance for centrally mediated responses such as circadian entrainment. We aimed to determine whether the information generated by melanopsin is also used by the visual system as a signal for light adaptation.

Abnormal Sleep in Chronic Inflammatory Demyelinating Polyneuropathy
European Journal of Neurology, Volume 32, Issue 11, November 2025.Beyond subjectively reduced sleep quality, actigraphic data show that persons with chronic inflammatory demyelinating polyneuropathy (CIDP) have a lowered sleep efficacy and experience increased nocturnal arousals. This suggests that sleep disturbance is a genuine aspect of CIDP adding to the underrecognized problem of non‐sensorimotor symptoms in this

Rod photoreceptors drive circadian photoentrainment across a wide range of light intensities. [PDF]
, 2010 In mammals, synchronization of the circadian pacemaker in the hypothalamus is achieved through direct input from the eyes conveyed by intrinsically photosensitive retinal ganglion cells (ipRGCs).

Molecular Ecology, Volume 34, Issue 21, November 2025.ABSTRACT Although mass, synchronised spawning of scleractinian corals is a well‐known phenomenon, its underlying molecular mechanisms, especially those that achieve synchronous release of gametes, are still unknown. In the genus Acropora, the dominant scleractinian coral in shallow reefs, spawning timing is synchronised in any given location, but often

Determination of Rod and Cone Influence to the Early and Late Dynamic of the Pupillary Light Response. [PDF]
, 2016 PURPOSE: This study aims to identify which aspects of the pupil light reflex are most influenced by rods and cones independently by analyzing pupil recordings from different mouse models of photoreceptor deficiency. METHODS: One-month-old wild type (WT),
