If you've ever tried to tickle yourself, you may not have succeeded. This is due to your nervous system suppressing the expected sensation of your own actions, a mechanism known as tactile gating. Until now, this mechanism ...
In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's brain, instruct ...
