LightTALKS!

Organizing local events will be one of the key ways that the international scientific community can spread IYL2015’s message about the importance of light and light-based technologies in our world. Find resources in the form of lightTALKS, collections of informative videos on interesting topics related to IYL2015.

Optical Illusions Show How We See
Beau Lotto's color games puzzle your vision, but they also spotlight what you can't normally see: how your brain works. This fun, first-hand look at your own versatile sense of sight reveals how evolution tints your perception of what's really out there.

A Light Switch for Neurons
Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness.
