- Neuroengineering Aims to Empower the Paralyzed and the Blind [MIT Technology Review]
“… by maneuvering his right shoulder in certain ways, Mumford could send signals through the stimulator and down his left arm into the muscles of his hand … He [Previously paralyzed] could open the refrigerator, take out a sandwich, and eat it on his own.
Advances in brain-machine interfaces and electrical–stimulation devices are generating marvelous research results in people with paralysis—some are using their thoughts to control robotic arms, and others are taking tentative steps.
250,000 people with spinal-cord injuries in the United States alone.
Retinal implant that can restore sight to people with a hereditary form of blindness. Potential market is quite big—perhaps 1.5 million people worldwide and 100,000 in the United States“
