When solving math problems, blind people rely on the same brain areas as sighted people. But blind people also pull in parts of the brain that others use only for vision, scientists reported September 16 in Proceedings of the National Academy of Sciences.

….However, the blind participants also tapped other “visual” brain areas that the sighted participants did not activate while performing calculations. This ability to repurpose brain areas that otherwise would be used for vision suggests that these regions are shaped by experience.
