Color-dependent changes in humans during a verbal fluency task under colored light exposure assessed by SPA-fNIRS [PDF]

open access: yesScientific Reports, 2021
Light evokes robust visual and nonvisual physiological and psychological effects in humans, such as emotional and behavioral responses, as well as changes in cognitive brain activity and performance.

The Role of Systemic Physiology in Individual Hemodynamic Responses Measured on the Head Due to Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: An SPA-fNIRS Study [PDF]

open access: yesBrain Sciences, 2022
In our previous investigations using systemic physiology augmented functional near-infrared spectroscopy (SPA-fNIRS) neuroimaging, we found larger variability between subjects in changes of cerebral hemodynamics and oxygenation induced by an intricate ...

Individual Differences in Hemodynamic Responses Measured on the Head Due to a Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: A SPA-fNIRS Study [PDF]

open access: yesBrain Sciences, 2021
When brain activity is measured by neuroimaging, the canonical hemodynamic response (increase in oxygenated hemoglobin ([O2Hb]) and decrease in deoxygenated hemoglobin ([HHb]) is not always seen in every subject.

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

open access: yesNeurophotonics, 2017
There is not yet a comprehensive view of how the color of light affects the cerebral and systemic physiology in humans. The aim was to address this deficit through basic research. Since cerebral and systemic physiological parameters are likely to interact, it was necessary to establish an approach, which we have termed "systemic-physiology-augmented ...

Colored Light Exposure Ensues Chronotype-Based Responses: Evidence From QEEG Analysis. [PDF]

open access: yesPhysiol Res
Light spectra, an imperative zeitgeber, may differ in its chronobiological effects among chronotype ensuing differences in circadian pacesetting. With the increasing usage of colored lights in the environment, the effects of light wavelength on the electrical activity of the brain among chronotypes need to be investigated.

Light-Dependent Effects of Prefrontal rTMS on Emotional Working Memory

open access: yesBrain Sciences, 2021
Growing evidence suggests that colored light exposure can affect several brain functions in addition to conscious visual perception. Blue as compared to green light has especially been shown to enhance alertness and vigilance, as well as cognitive ...

A Drowsiness Reduction Strategy Utilizing Visual Stimulation With Different Colors of Light: An fNIRS Study

open access: yesIEEE Access, 2021
Drowsiness during driving is a severe problem that must be addressed to improve road safety. Numerous counter-measures have been proposed to resolve this issue like adaptive environmental settings (temperature, sound, and light).

Alterations in lifespan and sleep:wake duration under selective monochromes of visible light in Drosophila melanogaster

open access: yesBiology Open, 2022
Rapid technology development, exposure to gadgets, and artificial lights (with different monochromes) have disturbed our lifestyle and the circadian clock, which otherwise confers better regulation of behavioral patterns and sleep:wake cycles in most ...
