Neurogenetics and auditory processing in developmental dyslexia.
نویسندگان
چکیده
Dyslexia is a polygenic developmental reading disorder characterized by an auditory/phonological deficit. Based on the latest genetic and neurophysiological studies, we propose a tentative model in which phonological deficits could arise from genetic anomalies of the cortical micro-architecture in the temporal lobe.

Processamento temporal auditivo: relação com dislexia do desenvolvimento e malformação cortical****** Temporal auditory processing: correlation with developmental dyslexia and cortical malformation
Background: temporal auditory processing and developmental dyslexia. Aim: to characterize the temporal auditory processing in children with developmental dyslexia and to correlate findings with cortical malformations. Method: twenty school-aged children, ranging in age from 8 to 14 years were evaluated. These children were divided into two groups: the experimental group (EG) was composed by 11 ...
متن کاملAuditory Processing of Amplitude Envelope Rise Time in Adults Diagnosed With Developmental Dyslexia
Studies of basic (nonspeech) auditory processing in adults thought to have developmental dyslexia have yielded a variety of data. Yet there has been little consensus regarding the explanatory value of auditory processing in accounting for reading difficulties. Recently, however, a number of studies of basic auditory processing in children with developmental dyslexia have suggested that a reduce...
متن کاملReduced sensitivity to slow-rate dynamic auditory information in children with dyslexia.
The etiology of developmental dyslexia remains widely debated. An appealing theory postulates that the reading and spelling problems in individuals with dyslexia originate from reduced sensitivity to slow-rate dynamic auditory cues. This low-level auditory deficit is thought to provoke a cascade of effects, including inaccurate speech perception and eventually unspecified phoneme representation...
متن کاملNeural correlates of rapid auditory processing are disrupted in children with developmental dyslexia and ameliorated with training: an fMRI study.
PURPOSE Developmental dyslexia, characterized by unexpected difficulty in reading, may involve a fundamental deficit in processing rapid acoustic stimuli. Using functional magnetic resonance imaging (fMRI) we previously reported that adults with developmental dyslexia have a disruption in neural response to rapid acoustic stimuli in left prefrontal cortex. Here we examined the neural correlates...
متن کاملPsychophysical indexes of temporal processing abnormalities in children with developmental dyslexia.
Children with dyslexia and children progressing normally in reading performed several perceptual tasks to determine (a) the psychophysical measures that best differentiate children with dyslexia from children with average reading abilities; (b) the extent of temporal processing deficits in a single, well-defined group of children with dyslexia; and (c) the co-occurrence of visual and auditory t...
