However, duration effect of blue light exposure during the developmental period of melanopsin ipRGCs is still unknown. Twenty four Swiss-Webster pregnant mice exposure to 470 nm blue light spectrum of the LED lights and sunlight. As a control group pregnant mice was keep in no light condition. The length of exposure was varies based on the stage of development: (1) from gestation day 9 (E9) up to 18 days of gestation (E18), (2) newborn to 6 days old, (3) from gestation day 9 until aged 6 days old. At 6 days old, selected mice pups were performed for negative phototaxis using cylindrical bore assay. The sunlight mice groups showed that the fastest response occur on longer exposure. However, on blue light mice groups, the longer the exposure actually decreases the activity more compare to only postnatal exposure. These conditions maybe due to interference on synaptogenesis during developmental period of melanopsin ipRGCs. Thus it can be concluded that exposure to blue light since in utero until neonatal is harmful especially to NIF response behavior.[/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]Blue light,Cumulative exposures,Cylindrical bore,Melanopsin,mice,negative phototaxis,Postnatal exposure,Response behavior[/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,melanopsin ipRGCs,mice,negative phototaxis[/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]The authors gratefully acknowledge funding from Ministry of Research, Technology and Higher Education of the Republic of Indonesia.[/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/10.1088/1755-1315/197/1/012053[/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]
