Neurally dissociable cognitive components of reading deficits in subacute stroke

This study represents progress toward identifying brain lesion-deficit relationships in the cognitive components of reading expected to help not only better understand the neural mechanisms of reading, but may also help tailor reading therapy to individual neurocognitive deficit profiles.

A developmental fMRI study of reading and repetition reveals changes in phonological and visual mechanisms over age.

These results are consistent with decreasing reliance on phonological processing, and increasing tuning of visual mechanisms, with age, and indicate that children and adults use largely overlapping mechanisms when processing high-frequency words.

Understanding the role of the prefrontal cortex in phonological processing

The findings for speech stimuli are consistent with the view that tasks that require increased articulatory recoding result in increased activation of the posterior aspect of the inferior frontal gyrus (BA 44), however, similar activation patterns for tone sequences as compared to speech may challenge whether the recoding is speech‐specific.

Segregation of Lexical and Sub-Lexical Reading Processes in the Left Perisylvian Cortex

Although half of the reading interferences found were nonspecific, the finding of specific lexical or sublexical interferences is new evidence that lexical andSublexical processes of reading could be partially supported by distinct cortical sub-regions despite their anatomical proximity.

Phonological dyslexia and dysgraphia: Cognitive mechanisms and neural substrates

Surface errors without semantic impairment in acquired dyslexia: a voxel-based lesion-symptom mapping study.

The data provide novel evidence for a post-semantic mechanism mediating the production of surface errors, and suggest that the posterior middle temporal gyrus may compute an intermediate representation linking semantics with phonology.

In cases in which national infant development screening tests have been conducted, as in Korea, if language developmental delay and early predictors of dyslexia are detected, careful observation of the progression to Dyslexia and early intervention should be made.

Two types of phonological reading impairment in stroke aphasia

This cross-sectional study tested whether the hallmark symptom of phonological reading impairment emerges from damage to a specific subprocess of phonology in stroke patients not selected for alexia syndromes and clarified that at least two dissociable phonological processes contribute to the pattern of reading impairment in aphasia.

Findings implicate left PITC as a possible neural substrate of the putative orthographic lexicon that contains stored memory representations for the written forms of familiar words.

Functional neuroimaging studies of reading and reading disability (developmental dyslexia).

This work proposes a neurobiological account suggesting that for normally developing readers the dorsal circuit predominates at first, and is associated with analytic processing necessary for learning to integrate orthographic features with phonological and lexical-semantic features of printed words.

Word and letter reading and the mechanism of the third alexia.

The residual reading of patients with severe Broca's or global aphasia and the "third alexia" appears to involve purely visual, nonphonetic mechanisms for word recognition, using posterior left hemisphere or even minor hemisphere centers.

Phonological and orthographic components of word recognition. A PET-rCBF study.

Correlations of reference voxels in the left superior temporal gyrus and left inferior frontal region with the rest of the brain were highly similar for the phonological and orthographic versions of each task type, consistent with connectionist models of reading, which hypothesize that both real words and pseudowords are processed within a common neural network.

The lack of a differential response in IFG for auditory processing supports its hypothesized involvement in grapheme to phoneme conversion processes and emphasizes the utility of examining both input modalities to compose a more complete picture of the language network.

The results illustrate that pseudowords place increased demands on areas that have previously been linked to lexical retrieval, and highlight the importance of including one or more baselines to qualify word type effects.

Dissociations support the view that two independent lexical routes are available for reading aloud familiar words, a semantic route and a lexical phonological route, which suggests that the reading aloud of non-words is not reliant upon grapheme-phoneme rules.
