The Neurocircuitry for Reading TEMPOROPARIETAL (DORSAL) Anterior (frontal) OCCIPITOTEMPORAL (VENTRAL)

Neurotrajectories in Reading Development Temporoparietal Increases in age and reading skill are associated with increased specialization of left hemisphere posterior brain regions Question: Given age-related changes in experience and plasticity how will this differ in adult learners? Anterior Occipitotemporal

The Neurobiology of Reading Disability Functional/structural neuroimaging indicate that poor readers, especially children, adolescents, and adults with reading disabilities fail to organize left hemisphere temporoparietal and occipitotemporal brain regions into a coherent reading circuit: 1) unstable and reduced brain activation 2) reduced connectivity 3) problems in learning, and consolidation of new learning 4) reduced grey matter volume 5) white matter tract anomalies

Instruction and the Neurocircuitry for Reading A growing number of studies with children and young adolescents have shown that effective remediation is associated with at least partial “normalization” of the neurocircuitry for reading. Question: Given age-related changes in brain plasticity and experience how might this differ in adult struggling readers?
