Nocturnal blue light exposure increase alpha and beta brain waves as cognition function for two consecutive night driving in a car simulator

Driving is a complex activity that engage complex motor, sensor, and cognitive function which can be analyzed through brain wave using electroencephalograph (EEG). Decrease of cognitive function while driving in long period at night linked with drowsiness and exposure of blue light to driver in nigh...
