University of Washington researchers used a direct brain-to-brain connection to enable pairs of participants to play a question-and-answer game by transmitting signals from one brain to the other over the Internet. The experiment is thought to be the first to show that two brains can be directly linked to allow one person to guess what’s on another person’s mind.
Neuroscientists at Stanford University have developed a technique that continuously corrects brain readings, resulting in a more precise way to type using a thought-controlled cursor. The researchers found that their technique is nearly as good as one-finger typing. Promising results have been obtained with monkeys, and a pilot clinical trial for human use is underway.
