Developmental dyslexia is characterized by an unexpected difficulty in reading in children and adults who otherwise possess the intelligence and motivation considered necessary for accurate and fluent reading. Recent advances in imaging technology provide the potential for elucidating a biological signature for reading and reading disability.
Bennett A. Shaywitz, M.D. is a leader in applying functional magnetic resonance imaging (fMRI) to understand the neurobiology of reading and dyslexia in children and adults. These studies identify a neural signature for dyslexia, making a previously hidden disability visible, and for the first time demonstrate the brain basis for the accommodation of extra time needed by dyslexic readers on high-stakes standardized tests. Shaywitz is currently using fMRI to investigate attentional mechanisms in dyslexia.
Our research group uses functional magnetic resonance imaging (fMRI) to examine the brain organization for reading including:
- Identification and localization of specific systems;
- Differences in good and poor readers;
- Computational role of each system;
- Plasticity, i.e., response to intervention;
- Types of reading disability.
