A meta-analysis of functional reading systems in typically developing and struggling readers across different alphabetic languages

Pollack, C., Luk, G., & Christodoulou, J. A. (2015). A meta-analysis of functional reading systems in typically developing and struggling readers across different alphabetic languages. Frontiers in Psychology, 6, 191. https://doi.org/10.3389/fpsyg.2015.00191

Summary: This meta-analysis of reading brain activation in typical and atypical readers of English, Dutch, Italian, German, French, and Norwegian showed common and distinct regions of activation, and support the universality of a signature pattern of brain activation in developmental dyslexia across alphabetic languages.

Annals of Neurology, 77(3), 487–503. https://doi.org/10.1002/ana.24343

Summary: Our findings indicate that patients with epilepsy from gray matter heterotopia have altered cortical physiology consistent with hyperexcitability, and that this abnormality is specifically linked to the presence of aberrant connectivity.

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). Brain bases of reading fluency in typical reading and impaired fluency in dyslexia. PLoS One, 9(7), e100552. https://doi.org/10.1371/journal.pone.0100552

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.
