Readers with dyslexia have disrupted network connections in the brain, map the circuitry of dyslexia shows

Dyslexia, the most commonly diagnosed learning disability in the United States, is a neurological reading disability that occurs when the regions of the brain that process written language don't function normally. The use of non-invasive functional neuroimaging tools has helped characterize how brain activity is disrupted in dyslexia. However, most prior work has focused on only a small number of brain regions, leaving a gap in our understanding of how multiple brain regions communicate with one another through networks, called functional connectivity, in persons with dyslexia. Scientists have now conducted a whole-brain functional connectivity analysis of dyslexia using functional magnetic resonance imaging (fMRI).
