Evoke of The Motoric Brain Waves of Driver in Car Simulator at Night by Blue Light Exposure and Visual Distraction

Driving at night need high levels of concentration for respond any visual stimulation by motoric coordination. Such concentration while driving can be mounted using blue light inside the car’s compartment, since it can inhibit the secretion of melatonin hormone, to increase drivers’ alertnessand prevent drowsiness at night. This study was aimed to evaluate the effect of blue light exposure on µ brain waves while driving at night in the simulator as a response to visual distraction. Brain waves data were recorded using electroencephalograph in brain motor areas from 7 men with predetermined criteria. Data were taken at night (7-9 pm) for 330 seconds in dark condition and blue light exposure, followed by the appearance of visual distraction automatically at 120 and 270 seconds and should be responded by braking. In blue light condition, µ brain waves were fluctuated in both motor areas since the first appearance of blue light exposure and was significantly different when compared to dark condition (p<0.05). It is concluded that blue light exposure at night in a driving simulator may increase drivers’ brain activity in the motor areas when responding to visual distraction, especially in the first appearance.
