Alteration in the visual and neural pathway persistence in early and late blind subjects during the cognitive processes would help in understanding the learning abilities of blind subjects and their training requirements. This can be assistance in their quality of life and adaptability to the surroundings. Functional imaging of congenital and late blind patients showed a cross-modal recruitment of the occipital cortex during the realization perceptual tasks such as Braille reading, tactile perception and spatial exploration.
