This article explains what Braille is: a system of raised dots that can be read with the fingers by people who are blind or who have low vision. Braille is not a language, but rather a code used to represent language in literacy. Braille is often written in 'uncontracted braille,' which is more common in younger kids or newly blind/visual impaired people and included entire words represented in braille, whereas 'contracted braille' is a shortened form that can use just the first and last letters of a word, respectively.

"The more he uses technology, the less he uses Braille ... technology is making the nearly 200-year-old writing system more accessible than ever. She shows off an electronic reader that's about the size of a paperback. Instead of having to lug around massive volumes of printed braille, this reader allows Deden to just sweep her fingers over little plastic nubs that rise and fall with each line of text. ... The federation estimates that today only 1 in 10 blind people can read Braille. That's down dramatically from the early 1900s."

Many languages are endangered. Braille and sign language may be next. Technological advancements have decreased demand for these once revolutionary aids.

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex. That division of labor suggests that the brain's structure follows a predetermined, genetic blueprint. However, evidence is mounting that brain regions can take over functions they were not genetically destined to perform. In a landmark 1996 study of people blinded early in life, neuroscientists showed that the visual cortex could participate in a nonvisual function - reading Braille. Now, a study from MIT neuroscientists shows that in individuals born blind, parts of the visual cortex are recruited for language processing. The finding suggests that the visual cortex can dramatically change its function - from visual processing to language - and it also appears to overturn the idea that language processing can only occur in highly specialized brain regions that are genetically programmed for language tasks. "Your brain is not a prepackaged kind of thing. It doesn't develop along a fixed trajectory, rather, it's a self-building toolkit. The building process is profoundly influenced by the experiences you have during your development," says Marina Bedny, an MIT postdoctoral associate in the Department of Brain and Cognitive Sciences and lead author of the study, which appears in the Proceedings of the National Academy of Sciences the week of Feb. 28.

"The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study... Brain imaging studies of blind people as they read words in Braille show activity in precisely the same part of the brain that lights up when sighted readers read."
