“…Dougherty et al (2007), Robichon and Habib (1998), and Rumsey et al (1996) all reported reduced white matter in the corpus callosum. Carreiras et al (2009) concluded in their paper that white matter differences in the corpus callosum are likely to be a consequence of differences in reading experience rather than the cause of reading difficulties.…”

(2018) Distinguishing cause from effect -many deficits associated with developmental dyslexia may be a consequence of reduced and suboptimal reading experience, Language, Cognition and Neuroscience, 33:3, 333-350, DOI: 10.1080/23273798.2017 The cause of developmental dyslexia is still unknown despite decades of intense research. Many causal explanations have been proposed, based on the range of impairments displayed by affected individuals. Here we draw attention to the fact that many of these impairments are also shown by illiterate individuals who have not received any or very little reading instruction. We suggest that this fact may not be coincidental and that the performance differences of both illiterates and individuals with dyslexia compared to literate controls are, to a substantial extent, secondary consequences of either reduced or suboptimal reading experience or a combination of both. The search for the primary causes of reading impairments will make progress if the consequences of quantitative and qualitative differences in reading experience are better taken into account and not mistaken for the causes of reading disorders. We close by providing four recommendations for future research.ARTICLE HISTORY

“…The corpus callosum may be a particularly important neural pathway in DD since children and adults with DD likely need to rely on the corpus callosum to recruit right hemisphere homologs during reading and reading-related tasks as a compensatory mechanism [33,[50][51][52][53].…”

Learning to read is an essential life skill, yet many children struggle and may even fail to learn to read. Developmental dyslexia (DD) is a specific learning disorder characterized by deficits in reading and reading-related tasks. Even though early intervention is crucial for successful remediation, many children do not receive a diagnosis until second grade or later. Research has shown high heritability of DD. Additionally, a link has been established between early language abilities and the development of reading skills. Moreover, individuals with DD display differences in neural structures implicated in reading even prior to learning to read compared to their typically developing peers. The aim of this review is to identify genetic, language, and brain predictors of reading.

“…Adopting a Darwinian thinking, it seems indeed plausible that the connectivity across and within modalities afforded by the peculiar structure of the Corpus Callosum is evolutionarily significant. In the case of auditory processing, it has been experimentally shown that it is the posterior Corpus Callosum that gives rise to this linguistically-crucial theta-gamma coupling (Rumsey et al, 1996;Pollmann et al, 2002;. Even early dichotic listening experiments on patients with Corpus Callosum abnormalities had specified that agenesis in the splenium is pertinent to aberrant auditory interplay (Sugishita et al, 1995;Pollmann et al, 2002).…”
