Thinking More in Dyslexia

Interesting stuff about dyslexics and analytical processing. There’s a great MRI scan on the blog too. Well worth having a look.

Thinking More in Dyslexia

It’s nice to see more data about non-reading differences and dyslexia. At right, MIT researchers found that dyslexic groups didn’t just have less active signals in the posterior pathways important for sound-letter correlations; they also had more activation in prefrontal cortex. And these differences were seen even if dyslexic and non-dyslexic subjects were matched for reading ability.

One possibility is that the extra prefrontal cortex reflects the extra effort (e.g. working memory) required to read to a certain level of proficiency; it’s also possible more activation is because dyslexics are using more analytical skills in the reading process.
