Visual cortical prosthesis will bring sight to the blind

Orion Cortical Visual Prosthesis System

American scientists (Baylor College of Medicine, University of California, Los Angeles and Second Sight Medical Products) have created a visual cortical prosthesis to help blind people see. And although this study is in its initial stages, blind patients already recognize points of light on the monitor. The device is called Orion and its principle of operation is quite simple: the visual information is fixed by the camera on the glasses and, bypassing the non-working optical nerves, is transmitted directly to the Orion device, which is implanted in the brain of the patient.

Researchers at the Swiss Federal Institute of Technology in Lausanne have created an artificial fingertip that is connected directly to the nervous systems of an amputee. Using a fingertip covered with high-tech sensors, a patient has been able to feel different textures, grainy and smooth surfaces. The engineers have already integrated the bionic fingertip into a prosthetic hand.

Mind-controlled prosthesis

Engineers from Johns Hopkins University have developed mind-controlled prosthetic arm that can move fingers individually and independently of each other. This is really good news for people with disabilities who have lost arms due to disease or injury. The young man on the video below was equipped with a device that use a brain-computer interface to control of his own arm and hand.

Implantable brain device to enable direct recording from neurons

A research team from DARPA’s Reliable Neural-Interface Technology (RE-NET) program has created a new implantable brain neural-recording device that can help paralyzed people move again. This novel device can be implanted into the brain and enable direct recording from neurons! Great advantage of the new technology is that the neural-recording device is installed into the brain through blood vessels, reducing the risks of classical invasive surgery and brain trauma.
