摘要Developmental dyslexia is a specific learning disability. The cerebral mechanism of development dyslexia is an important topic that has fascinated many researchers. With tie introduction of brain imaging in studies of cerebral mechanism of development dyslexia, many achievements have been made. Studies of developmental dyslexia structure image found that development dyslexia showed brain structure abnormal in the parietotemporal region, occipitotemporal cortex, inferior frontal gyrus, and cerebellum et al, manifesting either in one specific area or by the asymmetry of one area; the functional image studies revealed that development dyslexia showed activity abnormal in most regions that proved to display structure abnormality; studies of brain functional connectivity demonstrates that the abnormality of development dyslexia happened not only in the connection between front-back part in one cerebral hemisphere, but also in the connection between the two hemispheres. In addition, some studies indicate Chinese development dyslexia has different brain mechanisms compared to that of alphabetic languages. These findings provide valuable insight for future developmental cerebral mechanisms research and for the expansion of Chinese development dyslexia research.; Developmental dyslexia is a specific learning disability.
