When someone is blind from birth, what happens in their brain’s visual cortex? Scientists have long thought that this portion of the brain was repurposed, processing the input from a sense other than sight. But technology designed to help blind people “see” using soundscapes tells a different story. Brain scans in blind individuals using this system reveal vision-related brain activity similar to that in sighted people.
