CRS Guest Talks, Best Poster Prizes & Travel Awards > TED Talks > Ed Boyden
Working with an extraordinary array of tools; from 3D printers to lasers to flasks of algae, Ed Boyden is creating new brains. A pioneer in the field of optogenetics, he is the founder and principal investigator of the synthetic neurobiology group at MIT.
Using a combination of lasers and genetic engineering, he implants brains with optical fibers that allow him to activate special proteins in specific neurons and see their connections. In addition to helping create detailed maps of brain circuitry, the engineering of these cells has been used to cure blindness in mice, and could point the way to cures for Parkinsons or Alzheimers, or to ways of connecting to the brain via prosthetics.
TED 2011: 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. On the horizon: neural prosthetics. Session host Juan Enriquez leads a brief post-talk Q&A.
