Electrodes capable of evoking vision and adapting in real time are implanted in the brains of two blind people
A team from the Miguel Hernández University of Elche and the Alicante Hospital has implanted a microelectrode array in the brains of two blind people. This array is capable of sending electrical stimuli that evoke visual perceptions, something that has been done before, and also of "reading" neuronal responses and adapting to them in real time. The system has allowed them to recognize various complex patterns, movements, shapes, and even some letters. According to the researchers, this new technology "can help make the difference between perceiving a flash and seeing the world." The results are published in the journal Science Advances.
