Paralysed man flies virtual drone using brain implant

Researchers have developed a device that let a 69-year-old man with paralysis fly a virtual drone using only his thoughts. The brain–computer interface (BCI) decoded the man’s brain activity as he imagined moving three groups of digits in real time. By associating neural signals with the movements of multiple fingers, the work builds on previous BCI research, most of which has focused on moving a single computer cursor or whole virtual hand.
