Scientists have already trained monkeys to move a robotic arm with the power of thought and to recreate scenes moving in front of cats by recording information directly from the feline’s neurons. But these processes involve implanting electrodes into their brains to hook them up to a computer.
Now Yukiyasu Kamitani, at ATR Computational Neuroscience Laboratories in Kyoto, Japan, and Frank Tong at Princeton University in New Jersey, US, have achieved similar “mind reading” feats remotely using functional MRI scanning.
