Speakers Russell Foster: Circadian neuroscientist
Why you should listen to him:
The research on light perception hits home as we age -- faced with fading vision, we also risk disrupted sleep cycles, which have very serious consequences, including lack of concentration, depression and cognitive decline. The more we learn about how our eyes and bodies create our sleep cycles, the more seriously we can begin to take sleep as a therapy.
"Even in animals and people in whom the rods and cones used for vision have been completely destroyed and who are otherwise totally visually blind, the pRGCs can still detect light to shift the circadian clock."Russell Foster, in the Guardian Read more about Russell Foster on the TED Blog »
