Link Found Between Resilience to Dyslexia and Gray Matter in the Frontal Brain

A new joint Tel Aviv University and University of California San Francisco study identifies the brain mechanism that accounts for the discrepancy between low decoding skills and high reading comprehension.
The research was led jointly by Dr. Smadar Patael of TAU’s Department of Communication Disorders and Prof. Fumiko Hoeft, who is currently at the University of California San Francisco and starts as director of the University of Connecticut’s Brain Imaging Research Center this fall. The research was recently published in PLOS One.
Measuring gray matter: The research points to a larger volume of gray matter in resilient readers in the part of the brain responsible for executive functions and working memory. This specific region, the dorsolateral prefrontal cortex (DLPFC) of the left hemisphere, is known as the “air traffic controller” or “conductor” of the brain. Gray matter is the darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites.
