The mysterious case of man who can read letters—but not numbers—exposes roots of consciousness
Ellen Contini-Morava comments:
This is fascinating, but too bad the story doesn't talk about the orthographic difference between a letter and a number. A number is a "semasiographic" symbol, representing an idea rather than a word (so someone can "read" the symbol 8 in lots of different, unrelated languages). A letter is a "phonographic" symbol, representing a sound. So it's not that surprising that they might be processed differently in the brain.
