melluransaThey're different, although related. After damage to the grapheme recognition part of the brain (which is interesting, he only lost "form," the letters; the actual language, syntax, and content were intact) he had to rely on motor and tactile input to read (like braille) completely changing from visual input to tactile and motor input.
What a change! And it amazes me that the brain can learn such a different technique to do something that was effortless before.
Writing is also visual, but the motor movement of the hands and arms definitely has a role, although not as effectual as how it looks. It shows that your brain was paying attention to how it felt to move your hand to write, but didn't pay enough attention to ever rely on it. Fascinating.
Now I'm typing with my eyes closed, and it IS possible, completely relying on my fingers and how it feels rather than watching my hands. What if I became blind, what if I had to do this all the time?
