Meg Coherence Imaging In Dyslexia: Activation Of Working Memory Pathways, Alfred Mansour
Master's Theses and Doctoral Dissertations
The aims of this dissertation are to 1) review the genetic, neurodevelopmental, structural, and functional brain imaging studies that are the foundations of our understanding of dyslexia and 2) investigate the pattern of activation and functional connectivity of neuronal networks critical in working memory in dyslexics by means of magnetoenchephalographic (MEG) coherence imaging. Dyslexics showed an early onset of activation in the precentral gyrus and the superior frontal gyrus, which differed from controls where activation was initiated in posterior cortical regions (supramarginal gyrus and superior temporal gyrus). Further, dyslexics showed lower normalized amplitudes of activation in the right superior temporal …
