TL;DR: This article found significant hypoactivation to both letters and false-fonts in the left fusiform gyrus in at risk children who subsequently developed reading impairment, but not in at-risk children who developed typical reading skills.

Reading: The Confluence of Vision and Language
Jason D. Yeatman,Alex L. White,Alex L. White +2 more
- 15 Sep 2021
TL;DR: The scientific study of reading has a rich history that spans disciplines from vision science to linguistics, psychology, cognitive neuroscience, neurology, and education as discussed by the authors, and it can be traced back to the early 20th century.

Brain dynamics of (a)typical reading development-a review of longitudinal studies.
Katarzyna Chyl,Gorka Fraga-González,Silvia Brem,Katarzyna Jednoróg +3 more
- 01 Feb 2021
TL;DR: A review of findings from longitudinal neuroimaging studies on typical and atypical reading development can be found in this article, where the authors suggest that reading development results in increased structural integrity and functional specialization of left-hemispheric language areas.
Faces and words are both associated and dissociated as evidenced by visual problems in dyslexia.
TL;DR: This paper found that dyslexic readers tended to be poorer than typical readers at feature-based face matching while no differences were found for global form face matching, while processing the global form of faces apparently shares minimal-if any-resources with visual word processing.
Neural patterns of word processing differ in children with dyslexia and isolated spelling deficit

TL;DR: In this article, the authors investigated whether the neural substrates of word processing differ in children with various patterns of reading and spelling deficits, using functional magnetic resonance imaging, and found that children with dyslexia exhibited hypoactivations in the ventral occipito-temporal cortex compared to typical readers and spellers.
Words as Visual Objects: Neural and Behavioral Evidence for High-Level Visual Impairments in Dyslexia.
TL;DR: In this article, the authors argue that reading problems of some people with dyslexia can be a salient manifestation of a more general deficit of high-level vision, i.e., the processes that support visual recognition despite innumerable image variations, such as in viewpoint, position, or size.

From genes to behavior in developmental dyslexia
TL;DR: This work proposes a tentative pathway between a genetic effect, developmental brain changes, and perceptual and cognitive deficits associated with dyslexia and suggests some of the brain changes cause phonological processing abnormalities as well as auditory processing abnormalities.

A Meta-analysis of Functional Neuroimaging Studies of Dyslexia
José M. Maisog,Erin R. Einbinder,D. Lynn Flowers,D. Lynn Flowers,Peter E. Turkeltaub,Guinevere F. Eden +5 more
TL;DR: Findings suggest that during the performance of a variety of reading tasks, normal readers activate left‐sided brain areas more than dyslexic readers do, whereas dyslexia is associated with greater right-sided brain activity.

Connectivity precedes function in the development of the visual word form area

TL;DR: It is suggested that early connectivity instructs the functional development of the visual word form area, possibly reflecting a general mechanism of cortical development.

A qualitative and quantitative review of diffusion tensor imaging studies in reading and dyslexia
TL;DR: A quantitative activation likelihood estimation (ALE) meta-analysis on all reported studies that used a voxel-based approach reveals a cluster located close to the left temporoparietal region that demonstrates that this region hosts both the left arcuate fasciculus and the left corona radiata.

Unstable Representation of Sound: A Biological Marker of Dyslexia
Jane Hornickel,Nina Kraus +1 more
TL;DR: It is shown that poor readers have significantly more variable auditory brainstem responses to speech than do good readers, independent of resting neurophysiological noise levels, and that neural variability may be an underlying biological contributor to well established behavioral and neural deficits found in poor readers.
