Brain bases of reading fluency in typical reading and impaired fluency in dyslexia
Christodoulou, J. A., Del Tufo, S. N., Lymberis, J., Saxler, P. K., Ghosh, S. S., Triantafyllou, C., Whitfield-Gabrieli, S., & Gabrieli, J. D. (2014).

Summary: We identified the neural correlates of fluent reading in adults with and without dyslexia. Findings suggest a brain basis for impaired reading fluency in dyslexia, specifically a difference in brain activations related to semantic retrieval and semantic and phonological representations at rapid reading rates.
