Aired 9/28/15 on KPBS News. The same kind of sound waves used in sonograms now allows researchers to change a worm’s behavior. You ever get the feeling sounds are controlling your mind? Maybe a catchy song gets stuck in your head. Or a noisy neighbor won’t stop driving you nuts. Well, sounds may not literally control your mind. But in the field of neuroscience, a new technique is actually giving researchers the power to control specific brain cells using sound waves. Don’t reach for a tinfoil hat just yet. So far, sound control only works on very small brains. “So let me zoom in,” says Salk Institute neuroscientist Sreekanth Chalasani as he pulls up a magnified view of the tiny C. elegans worm. “It’s only a millimeter long,…
