Physiological and anatomical evidence for a magnocellular defect in developmental dyslexia.
Physiological and anatomical evidence for a magnocellular defect in developmental dyslexia.
Several behavioral studies have shown that developmental dyslexics do poorly in tests requiring rapid visual processing. In primates fast, low-contrast visual information is carried by the magnocellular subdivision of the visual pathway, and slow, high-contrast information is carried by the parvocellular division. In this study, we found that dyslexic subjects …
