The area of the brain which is used to process reading is not reliant on vision, a recent study has claimed.
Research carried out by the Hebrew University of Jerusalem and published in the online edition of Current Biology compared brain imaging studies of sighted and blind people.
The findings showed that the area of the brain that is active when people read words from a printed page also lights up when blind people read in Braille.
Amir Amedi of the Hebrew University of Jerusalem said the project suggests the brain is a "task machine" rather than solely being a sensory organ.
"A brain area can fulfil a unique function, in this case reading, regardless of what form the sensory input takes," he explained.
Also recently, research by the Wellcome Trust Centre for Neuroimaging at University College London, which was published in the journal Nature Neuroscience, suggested that how people see the world around them depends on the size of the part of the brain which processes visual data.
