Light and the circadian system: from retina to the brain and behavior

June 2, 2022

Strasbourg (France)


Environmental light, and in particular day-night alternation, has a high impact on physiology and behavior of living organisms. The function of the retina,the light entry site into the organism, is pervasively controlled by light itself, from gene expression to metabolism and network organization. Downstream of the retina, the brain is the major target of light that not only drives the function of the central body clock, but also regulates sleep, mood and cognition.
