Newly published research successfully created a form of artificial vision for a blind woman using a prosthesis hardwired into her brain. The team conducted a series of experiments with a blind person for six months in Elche, Spain, that represent a leap forward for scientists hoping to create a visual prosthesis that could increase independence for the blind.
A microelectrode array, the Utah Electrode Array (UEA), was implanted into the visual cortex of the blind person to record and stimulate the electrical activities of neurons. The patient wore eyeglasses equipped with a miniature video camera; specialized software encoded the visual data collected by the camera and sent it to the UEA.
