Effect of short-term colored-light exposure on cerebral hemodynamics and oxygenation, and systemic physiological activity

It was shown that short-term light exposure caused color-dependent responses in cerebral hemodynamics/oxygenation as well as cardiorespiratory dynamics, and neurosystemic functional connectivity changes even during apparently stress-free tasks.

Exposure to Artificial Light at Night and the Consequences for Flora, Fauna, and Ecosystems

The present review draws together wide-ranging studies performed over the last decades that catalogue the effects of artificial-light-at-night (ALAN) upon living species and their environment to discuss how society should take into account the potentially major consequences that ALAN has on the natural world and the repercussions for ongoing human health and welfare.

Transcranial bright light treatment via the ear canals in seasonal affective disorder: a randomized, double-blind dose-response study

Results suggests that transcranial bright light treatment may have antidepressant and anxiolytic effect in SAD patients, as both self- and psychiatrist-rated depressive and anxiety symptoms decreased in all treatment groups.

Transcranial bright light and symptoms of jet lag: a randomized, placebo-controlled trial.

Results suggest a cumulative effect of TBL, as the effects emerged on post-travel days 3-4, as well as a significant reduction of overall jet lag symptoms, subjective sleepiness, and the fatigue, inertia, and forgetfulness subscales of the POMS when comparing the active TBL treatment group to the placebo group.

A Novel Human Opsin in the Inner Retina

The unique inner retinal localization of melanopsin suggests that it is not involved in image formation but rather may mediate nonvisual photoreceptive tasks, such as the regulation of circadian rhythms and the acute suppression of pineal melatonin.

The evolution of irradiance detection: melanopsin and the non-visual opsins

The range of vertebrate photoreceptors and their opsin photopigments are discussed, the melanopsin/pRGC system is described in some detail and the molecular evolution and sensory ecology of these non-image-forming photoreceptor systems are considered.
