非視覚機能に及ぼす錐体の働きに関する最近の研究動向

抄録

In the field of physiological anthropology, studies on the non-visual effects of light have been conducted since the early 1990s. Although intrinsically photosensitive retinal ganglion cells (ipRGCs) are thought to be primarily involved in non-visual functions, recent studies in animals and healthy humans have revealed that cones may also contribute to non-visual functions such as circadian entrainment, suppression of melatonin secretion, and pupillary light reflex. In this paper, we reviewed recent studies on the role of cones in these non-visual functions.
