Breakthrough helps restore vision for the blind

Researchers in Texas have taken a big step in restoring vision for blind people by transferring information directly to the brain via electrodes.

A team at Baylor College of Medicine in Houston, USA, led by scientist Daniel Yoshor, has developed a type of nerve implant that allows visually impaired people to see the contours and letters through images. camera to the brain.

A visual prosthetic prosthesis that allows the blind to fully regain their vision is still a matter of the future, but with recent research, the blind can see the basic shapes.

"When we use electrical stimulation to deliver text signals directly to the patients' brains, they can" see "the letter shapes and correctly identify different letters. They describe seeing specks of light or lines forming letters is like writing in the sky, " said Yoshor.

Yoshor and his colleagues tested their system on four people with nearsightedness and two blinds. All subjects are able to accurately identify letters according to the information their brain receives.

Because the system uses only a limited number of electrodes, the next goal the team aims to develop is a new system next to the nerves with thousands of electrodes that allow more precise brain stimulation. Creating more accurate images in the user's brain.

Although still in the early stages of development, the researchers expect to be able to come up with a superior system that enables visually impaired people to "sketch" family members and their relatives.
