Scientists give blind people ‘sight’ by drawing shapes directly on their brains

A team of researchers from UCLA and Baylor have developed a method for drawing symbols – including letter and shapes – directly on the human brain using electrical stimulation. The result allows individuals who’ve entirely lost their sense of vision to perceive the shapes as “sights.” The new process bypasses the human eye and the optic nerve and uses electricity to stimulate implanted electrodes at the visual cortex, located in the back of the brain. It works through dynamic stimulation, meaning instead of sending stimulation in the shape of a completely formed letter, the researchers trace the letter directly on… This story continues at The Next Web
