Study on the Impact of Light on Human Physiology and Electroencephalogram

摘要

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 beenmade 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.
