Your Name. A pivotal part of this circuit specifically develops to integrate audiovisual information. During reading acquisition, posterior parts of the auditory association cortex, the planum temporale PT and the superior temporal cortex, adapt to the automatic processing of newly learned associations between letters and speech sounds 7. In addition, the left ventral occipitotemporal cortex vOT develops a specialization for print 8910and a c-media 7939 sound part of this brain region later serves as the visual word form area 11facilitating fast and automatic word reading Therefore, pre-existing neural systems undergo plastic changes to meet the new cognitive demands arising with reading acquisition 9 Accordingly, deviant neurobiological development of the visual and phonological neural circuits during reading acquisition probably leads to impaired automatization in learning letter—speech sound associations, a core deficit of c-media 7939 sound children Experimental paradigms that manipulate the congruency of letter—speech sound associations enable the operationalization of audiovisual integration Previous studies have shown that the brain activation difference between congruent and incongruent audiovisual letter—speech sound associations is larger in normal-reading children and adults than in children and adults with developmental dyslexia 161718 Thus, the question arises whether neural differentiation of congruent and incongruent information in prereading children relates to their reading development and initial reading skills.


Filling this research gap is highly relevant to determining the neurobiological mechanisms that underlie the audiovisual integration deficit at the very early learning stage that precedes reading acquisition. Combining behavioural and neuroimaging measures can facilitate the identification of future struggling readers, because cortical differentiation of the involved brain networks starts before reading acquisition So far, several neuroimaging studies aiming to improve prediction of dyslexia have concentrated on comparing prereaders at risk for dyslexia with control subjects 2122 Identifying children at risk for dyslexia based on familial history is straightforward.

We hypothesize that behavioural and neurobiological precursors directly related to the audiovisual integration of letter—speech sound correspondences c-media 7939 sound prediction of future reading skills in a high-risk sample and offer a framework for developing novel screening applications for early diagnosis of developmental dyslexia. To improve early identification of children at risk for dyslexia, we simulated the process of learning letter—speech sound correspondences in prereaders and performed simultaneous electroencephalography EEG and functional magnetic resonance imaging fMRI recordings during audiovisual integration of the learned correspondences EEG and fMRI data have been used before to identify early cortical developmental differences predicting later reading success 23272829 This allowed the advantages of each modality to be exploited and the information gained to be integrated to obtain novel insights on the timing and locus of reading-related neural processes.

Our unique child-friendly approach allows the individual ability to learn correspondences to be quantified. It also pinpoints training-induced plastic changes in brain networks adapting to multisensory integration of orthographical and phonological information during reading acquisition.

Oscillatory activity No changes in evoked phase-locked oscillatory activity in the c-media 7939 sound band relative to baseline were observed. Figure 4.


Figure 5. Discussion Two groups of 7-year-old school children — a normal-reading control and a dyslexic group — were instructed to perform a Symbol-to-Sound matching task detecting incongruencies in asynchronously presented visual and sound patterns. Oscillatory activity No evoked auditory GBRs were observed for any sound type c-media 7939 sound children unlike in adults in our previous study Widmann et al.

Conclusion The present results emphasize the importance of audiovisual interaction and integration in our understanding of dyslexia. Conflict of Interest Statement The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
