A rhesus macaque walks with the aid of a pneumatically powered exoskeleton controlled by a computer reading signals from electrodes implanted in the monkey’s motor cortex. Miguel Nicolelis and colleagues at Duke University are developing similar devices that could allow paralyzed humans to walk again.
Monkeys Steer Wheelchairs With Their Brains, Raising Hope for Paralyzed People.
Maryam Shanechi and her team at USC work on control systems, neuroscience and signal processing to develop brain machine interfaces. These interfaces are being used to help patients with neuropsychiatric disorders, aid in anesthesia administration, and contribute to the prosthetic limb development.

Medical device companies are coming out with dynamic neural stimulators that have a bit of “brain” themselves. These smart systems can detect changes in a physiological signal and then respond by delivering a therapy or adjusting the patient’s treatment in real time.

TENS stands for Transcutaneous Electrical Nerve Stimulation, a technology that applies a small electrical current to the surface of your skin—in the case of Quell, the electrical leads make contact with your calf, which Quell describes as a “veritable USB port” for plugging into your body’s nervous system.
Classic movies about memory manipulation, and how they inspired neuroscience research.

Brain implants today are where laser eye surgery was several decades ago. They are not risk-free and make sense only for a narrowly defined set of patients—but they are a sign of things to come.
