Optogenetics: Optics & Genetics Combine to Stimulate and Visualize the Nervous System

From Science news this week:
Shining New Light on Neural Circuits
by Greg Mille

"When researchers from Yale University reported last year that they'd used a laser to activate neurons in fruit flies and in turn control the insects' behavior, even Jay Leno thought it was cool. In a skit, the Tonight Show host pretended to use a remote-controlled fly to harass President George W. Bush during a speech. "I thought it was actually quite funny," says Gero Miesenböck, the neuroscientist who led the study. A video clip of Leno's skit elicited chuckles when Miesenböck played it during a presentation at October's meeting of the Society for Neuroscience in Atlanta, Georgia." [more from Science]
