| Research Abstract |
Purpose of this study was to propose and evaluate a new dynamic model of developmental dyslexia. Functional magnetic resonance imaging (fMRI) was employed to investigate the relationship between word reading learning and changes in brain activity. Compared to the later stage of word reading learning, the early stage showed greater activity in the bilateral posterior lateral inferior temporal gyrus, middle and superior occipital gyrus, and inferior frontal gyrus. The opposite contrast revealed greater activity in the bilateral supramarginal gyrus and angular gyrus. These results indicate that both the dorsal (sublexical route) and ventral stream (lexical route) participate in the early stage of word reading learning.
