From my dad's alma mater Case Western Reserve (it was just Case in dad's time) scientists allowed a man paralyzed from the neck down to scratch his nose (!), grasp a mug to drink and to eat mashed potatoes using his thoughts alone ! Reaching and grasping were accomplished by combining functional electrical stimulation with an intra-cortical brain-computer interface to create a connection between the man's brain and his paralyzed muscles.
