Researchers Establish Direct Brain-to-Brain Link Between Humans and Rats
it just experimented with a system that lets a human mind trigger actions in a rat’s motor cortex. The test had sensor-equipped humans watch a screen that flashed in sync with their EEG brain patterns for visual stimulation; as soon their attention shifted to controlling the rat, they triggered an ultrasonic pulse that twitched the rodent’s tail. There’s a few problems with the implementation beyond the obvious lack of autonomy for the poor target creature, though. The rat’s anaesthetized state likely affected the results, and the system isn’t currently sophisticated enough to map specific thoughts to corresponding actions.
