Anterior
Occipitotemporal
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?
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 activation2) reduced connectivity3) problems in learning, and consolidation of new learning4) reduced grey matter volume5) 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?
