.....researchers now know that the reading disability involves a weakness in the part of the brain that decodes the sounds of written language.
.....As readers become more skilled, an area further back in the brain, next to the visual processing area, starts to show greater activity.
Sally Shaywitz, a dyslexia expert at Yale University, says that is the "word form" area. As readers learn more and more words on sight, without having to sound them out, this area takes on an ever greater share of the reading task, she says.
"When we first learn how to read," she said, "it's effortful. But after you've read a word a certain number of times, those nerve endings come together and then it's stored in the word-form area."
