Robotic arm connected directly to brain of paralysed 28-year-old man.
Microelectrodes about half the size of a shirt button were surgically implanted in his brain.
He said it felt like “my fingers” were being touched or pushed.
Before the operation, imaging identified exact places that corresponded to sensations in his hand.
The ultimate goal is to create a system which moves and feels just like a natural arm would.
The study was published in the Science Translational Medicine journal.
