A mind-controlled robotic arm has pressure sensors in each fingertip that send signals directly to a paralyzed man's brain. It's still experimental, but could eventually help thousands, engineers say.
Monday, October 03, 2016
When a team of researchers evaluated the scientific literature on brain games, they found little evidence that the products improve memory or thinking in real-world tasks.
