Yakiyasu Kamitani of the ATR Computational Neuroscience Laboratories in Kyoto, Japan, has developed a robot hand that is controlled by the power of thoughts alone!
The robotic hand mimics the movements of a person's real hand, based on real-time functional magnetic resonance imaging (fMRI) of their brain activity. It marks another landmark in the advance towards prosthetics and computers that can be operating by thought alone.
