Stopping a planned behavior requires extremely fast choreography between several distinct areas of the brain, the researchers found. If we change our mind about taking that step even a few milliseconds after the original “go” message has been sent to our muscles, we simply can’t stop our feet. “We have to process all of these pieces of information quickly,” said … Continue reading
