With the help of magnetic resonance imaging (MRI) technology, researchers have recorded test subjects’ brain activity to create a robotic hand that mimics a human one. Subjects were asked to perform “rock, paper, scissor”-like motions with their hands while an MRI scanner recorded their brain activity. Scientists mapped this data onto a robotic hand, programming the faux appendage to mirror a real one based on its recognition of how brain activity corresponds to hand movement. Researchers say this thought-controlled robot is a groundbreaking for both computers and prosthetics.
