Blind use brain's visual areas to solve math problems
People born without sight have been found to solve math problems using visual areas of the brain, says new research.
Human babies and even animals have a basic sense for numbers that experts believe has nothing to do with vision.
The brain network behind numerical reasoning is identical in blind and sighted people. The research also found that the visual part of the brain in blind people is highly involved in doing math, which shows that the brain is very adaptable.
The researchers tested people who were blind from birth and people with sight in blindfolds. They were asked to solve math equations and answer language questions while having a brain scan.
