People who are blind from birth are able to detect tactile information faster than people with normal vision, according to a study in the Oct. 27 issue of The Journal of Neuroscience.
The brain requires a fraction of a second to register a sight, sound, or touch. In this study, a group of researchers led by Daniel Goldreich, PhD, of McMaster University explored whether people who have a special reliance on a particular sense - in the way blind people rely on touch - would process that sense faster.
”Our findings reveal that one way the brain adapts to the absence of vision is to accelerate the sense of touch,” Goldreich said. ”The ability to quickly process non-visual information probably enhances the quality of life of blind individuals who rely to an extraordinary degree on the non-visual senses.”
