Seeing words as pictures

Dyslexia: News from the web:

Skilled readers can quickly recognize words when they read because the word has been placed in a visual dictionary of sorts which functions separately from an area that processes the sounds of written words, say neuroscientists. The visual dictionary idea rebuts a common theory that our brain needs to “sound out” words each time we see them.

John Donoghue wants to fix your brain.

As director at the Wyss Center, Donoghue works in the field of neurotechnology – brain computer interfaces. While it sounds like the stuff of sci-fi, it’s not as distant a prospect as the idea might suggest.

What causes the difference between dyslectics?

Dyslexia: News from the web:

Variants in DCDC2 and several other neural migration genes are associated with dyslexia and may contribute to auditory processing deficits. In the current study, we tested the hypothesis that RNAi suppression of Dcdc2 in rats causes abnormal cortical responses to sound and impaired speech sound discrimination. In the current study, rats were subjected in utero to RNA interference targeting of the gene Dcdc2 or a scrambled sequence.
