This paper summarizes research currently being conducted on the biologic underpinnings of learning disorders, particularly dyslexia. The research findings discussed are derived from studying neuroanatomic, neurophysiologic, neurogenetic, neuroimaging, and behavioral characteristics in animal models that exhibit developmental brain anomalies and…

This paper reviews ongoing research designed to specify the cognitive, behavioral, and neuroanatomical phenotypes of specific genetic etiologies of learning disability. The genetic disorders at the focus of the research include reading disability, neurofibromatosis type 1, Tourette syndrome, and fragile X syndrome. Implications for identifying…

This paper discusses the results of two learning disabilities investigations conducted at the Yale Center: (1) research from longitudinal studies on the development of children not identified as having a disability and (2) neurobiological studies that employ functional magnetic resonance imaging. Other ongoing studies at the center are also…

This article reviews recent research in the field of learning disabilities and, in particular, dyslexia. It summarizes findings from numerous studies employing widely divergent methodologies that have attempted to establish the neurobiological correlates of learning disabilities and concludes that it is impossible to deny a neurobiological basis…
