Neuroscience of Visual Impairment

Our brain only requires a single second to determine what we’re seeing. The region in our brain that can arrange these visual observations so quickly is the so-called ventral-temporal cortex, the visual brain. It is found that blind people also use the map in the visual brain. Their Visual Brain acknowledge in a different way to each category. This means that blind people, too, use this part of the brain to differentiate between categories, even though they’ve never had any visual input.
