NERVE implants can help paralysed people perform simple tasks, such as
gripping a cup. But the lack of feedback means they can drop the cup or even

more effectively. They hope eventually to help restore sensation to those with
spinal injuries.
Without sensation, patients using neural prostheses have to rely upon their
