1. A team of scientists has given 'sight' to people who had completely lost their sense of vision. 2. Scientists from UCLA and Baylor developed a technique to relay visual information from cameras to the brain - by the way of electric signals. 3. The researchers used electricity to stimulate electrodes implanted at the visual cortex in the back of the brain. 4. In a test, the system worked almost perfectly for two blind subjects and four sighted people who had the implants as part of a treatment for epilepsy. 5. Specifically, they were given electric stimulation through the implant and were able to perceive the symbols with an incredible accuracy between 80% to 93% and they even managed to draw the symbols on a screen.
