Developmental dyslexia has come to be viewed as a language disorder involving phonologic deficits. This view has greatly influenced imaging studies of dyslexia, with the result that anatomic studies have primarily focused on language relevant brain structures and functional studies have examined language-related functions. Although inconsistent in their methods and findings, both neuroanatomic imaging studies using computed tomography and magnetic resonance imaging and postmortem studies, suggest that asymmetries of the planum temporale and other language-relevant structures, as well as the morphology of the corpus callosum, warrant further study using improved methods now available. Functional imaging studies using xenon inhalation techniques and positron emission tomography suggest altered left temporoparietal and bilateral temporal function. An emergent interest in difficulties with rapid temporal ( i.e. sequential) processing, particularly within the visual system, is also noteworthy. [ABSTRACT FROM AUTHOR]
