The purpose of this abstract is to compare the spectral properties of the fMRI signal changes in areas associated with phonological processing (inferior frontal gyrus (IFG) and angular gyrus (AG) ) in good and dyslexic readers. Our preliminary results indicate lack of temporal coherence between the right IFG and other regions studied here across the entire task. They also suggests possible functional discontinuity of the left IFG and right IFG in dyslexic readers and a possibly compensatory role of the left IFG in the reading strategies employed by dyslexics.
