Abstract

The intricate relationship between light exposure and brain development has been a subject of growing interest. Melanopsin retinal ganglion cells (mRGCs) are specialized photoreceptors that play a unique role in regulating nonimage-forming visual functions, including circadian rhythms and pupillary light responses. Recent research has revealed a compelling connection between mRGCs, light exposure, and the developing brain. This article reviews the latest findings on how mRGCs mediate light-promoted brain development, shedding light on their potential implications for various neurological and neuropsychiatric conditions
