Light shined on monkey brains shown to control behavior
Boston scientists advance field of optogenetics
A team of Boston scientists has altered the brain activity and behavior of monkeys with what sounds like science fiction -- blue flashes of light that directly activate brain cells. The technique, called optogenetics, has already transformed basic neuroscience research on addiction and memory conducted in mice and other simple organisms. But the new work shows it can be used to explore and probe complex brains capable of human-like tasks and vulnerable to some of the same problems.
