Study on the Impact of Light on Human Physiology and Electroencephalogram

Abstract

The influence of light on Electroencephalogram seems to be more critical, when physician depends on its readings to diagnose subject brain disorder according to its level. Although, bright light brings various changes in human physiological variables. But, Neurophysiological changes for specific light level still remain unclear. Thereby, in the present study, the response of brain electrical activity towards various light levels has been classified and verified. The reasons for alteration in different physiological variables due to bright light which results change in the state of electroencephalographic recordings has been reviewed. Additionally, the effects of bright light towards Ocular artifacts are also put forward. A novel hypothesis has been made using subjective analysis and experimental analysis in low luminance or darkness. It is observed that a poor lighting condition affects both behavioral task and brain activity.

Influence of white-light-emitting diodes on primary visual cortex layer 5 pyramidal neurons (V1L5PNs) and remodeling by blue-light-blocking lenses

“…Visible light plays a chief role in image forming [ 4 – 7 ] and non-image forming functions such as sleep/wake states, alertness, mood, and behavior [ 8 – 12 ]. Visible light has an acute impact on cortical functioning [ 13 – 15 ]. Due to their efficiency and durability, LEDs have become a predominant light source in recent years [ 16 ].…”

“…Animals in the exposure group were states, alertness, mood, and behavior [8][9][10][11][12]. Visible light has an acute impact on cortical functioning [13][14][15]. Due to their efficiency and durability, LEDs have become a predominant light source in recent years [16].…”
