Right and Left Handed Reading of Braille

IT is generally held that in right handed people the parietooccipital area of the left cortical hemisphere is important for the ability to read. It is also known that the right hemisphere contributes more to non-verbal, visual and spatial functions than does the left. A demonstration of this functional asymmetry was provided by Kimura1, who showed that subjects were more accurate in reporting the number of dots presented tachistoscopically the left than in the right visual field. Conversely, letters were identified better when they were presented to the right visual field; that is, the left hemisphere.
