A Scotish Woman by the name of Melina Canning who lost her sight 18 years ago due to a repristory infection is still able to see any object if it is in motion. This condition is very unusual, so much so that Neuroscientists at Western University’s Brain and Mind Institute had to conduct a special research to understand how can Ms. Canning do this. Judy Culham was the team leader of the Neuroscientists who did their tests and their conclusions were that Ms. Canning has a rare disease that is called Riddoch syndrome — that is, when a blind person can consciously see an object only when it is moving and not when it is not moving – this could be, in my humble opinion due to Ms. Canning using her inner psychic gift of vision as well of which neurologists haven’t a clue about – for example even if my bedroom is totally dark, I can see objects in my mind and remember their placement in the room!
“She is missing a piece of brain tissue about the size of an apple at the back of her brain — almost her entire occipital lobes, which process vision,” says Culham, a professor in the Department of Psychology and Graduate Program in Neuroscience.
- Scientists have long wondered whether we’re born with this map, or whether its development relies on the visual input that we receive.
- Their visual brain responds in a different way to each category. This means that blind people, too, use this part of the brain to differentiate between categories.
- But these findings also raise new questions. For one thing, sounds are very different from visual input such as images and videos, so what exactly is being processed in blind people’s visual brain
“The research shows the remarkable plasticity of the human brain in finding work-arounds after catastrophic injuries. And it suggests conventional definitions of ‘sight’ and ‘blindness’ are fuzzier than previously believed.”
