A scientific breakthrough restores "vision" to a blind person for the first time after 16 years

Spanish scientists have revolutionized medicine after a brain transplant stimulated the visual cortex of a blind woman, allowing her to "see" for the first time in 16 years.!!

The operation allowed the patient to see the light and the shapes again, using an "artificial retina" attached to a pair of glasses to direct the light in front of them. The light processing occurred then into electrical signals. The signals are then sent to a series of tiny electrodes implanted in the patient's brain, allowing the user to "see" the light captured by the glasses.

This system was tested on a 57-year-old woman who had not seen anything for 16 years, during which time she was completely blind.

The advanced implant enabled the woman to recognize the shapes and silhouettes detected by the artificial retina.

"We consistently obtained high-quality recordings from visually deprived neurons and the stimulation parameters remained stable over time," the scientists wrote in a research paper published in The Journal of Clinical Investigation.

The patient was also able to detect "some characters" and even "recognize the boundaries of an object," according to the scientists.
