WITH DEVELOPMENTAL DYSLEXIA by JULIANA SANCHEZ BLOOM (Under the Direction of George W. Hynd) ABSTRACT The planum temporale (PT) is a highly lateralized cortical region located within Wernicke’s area which is thought to be involved in auditory processing, phonological processing, and language. Research has linked abnormal morphology of the PT and its parietal extension, the planum parietale (PP)...

BACKGROUND Doublecortin domain-containing 2 (DCDC2) is a doublecortin domain-containing gene family member and the doublecortin domain has been demonstrated to bind to tubulin and enhance microtubule polymerization. It has been associated with developmental dyslexia and this protein family member is thought to function in neuronal migration where it may affect the signaling of primary cilia. ...

There is a continuum of cognitive styles amongst humans, defined by differences in minicolumnar numbers/width and arcuate/commissural white matter connectivities. Specifically, it is the connectivity within and between modular cortical circuits that defines conditions such as autism and developmental dyslexia. In autism, a model of local hyperconnectivity and long-range hypoconnectivity explain...

Developmental dyslexia is a language-based learning disability characterized by persistent difficulty in learning to read. While an understanding of genetic contributions is emerging, the ways the environment affects brain functioning in children with developmental dyslexia are poorly understood. A relationship between the home literacy environment (HLE) and neural correlates of reading has bee...

BACKGROUND Multiple lines of evidence have suggested that developmental dyslexia may be associated with abnormalities of neuronal migration or axonal connectivity. In patients with periventricular nodular heterotopia--a rare genetic brain malformation characterized by misplaced nodules of gray matter along the lateral ventricles--a specific and unexpected reading disability is present, despite ...

3 Abstract The present study describes two French teenagers with developmental reading and writing impairments whose performance was compared to that of chronological age and reading-age matched non-dyslexic participants. Laurent conforms to the pattern of phonological dyslexia: he exhibits a poor performance in pseudo-word reading and spelling, produces phonologically inaccurate misspellings b...

Articulatory disorders have been occasionally associated with developmental phonological dyslexia. This study used acoustic and aerodynamic data to investigate to what extent developmental dyslexia is associated with potential disorders in the fine-grained control of articulatory movements in voiced and voiceless bilabial stops /b/ and /p/ production in a repetition task. Our results reveal mor...

Several prenatal and perinatal factors have been found to be associated with developmental dyslexia (reading disorder) in alphabetic language. Given the absence of relevant studies of Chinese children, the present study tries to investigate these risk factors. A total of 45,850 students were recruited from grades three to six, from seven cities of Hubei province. Dyslexia in Chinese was diagnos...

Marshall (1984) highlighted potential parallels between children with developmental disorders of reading and adults who had acquired reading disorders. He advocated the use of a cognitive neuropsychological framework in the investigation of children with developmental abnormalities of cognition, including those with developmental dyslexias. Developmental phonological dyslexia has been extensive...
