All rights reserved.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 night-driving could improve cognitive function; yet, studies driving session on the car simulator with a straight and monotonous road for 2 consecutive nights for 30 min without pause. The participants were divided into three driving groups as follows: in dark condition (control), under exposure to polychromatic blue light (450-540 nm) and monochromatic blue LED light (460 nm). All participants’brain waves were recorded by EEG during the driving session from two channels of F3 and F4 representing cognitive function of the brain. The result showed that there was a significant increase of beta and alpha wave power spectral density on the second day of exposure in both blue light treatment groups. However, monochromatic blue light gave a more stable beta wave than the other two lights which incidate a much stronger cognitive process. There was also a synchronization from both channels of F3 and F4 in all treatments which shows that aplha and beta wave do not necessarily work in an antagonistic way. In summary, repeated, continuous exposure of blue light may increase aplha and beta wave power spectral density, in which monochomatic blue light cuses better cognitive state than polychromatic blue light.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Blue light,Brain wave,Driving simulator,EEG,Power spectral density[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.17576/jsm-2020-4909-07[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
