Disconnected links in brain may cause dyslexia A Harvard study has suggested a physical basis for dyslexia. The team mapped the brains of six sufferers of the genetic disorder periventricular nodular heterotopia (PNH), who show many of the symptoms of dyslexia. A normal brain has grey matter or nerve cells near its surface and white matter which connects the grey matter deeper inside. The team found that the brains they imaged were more disordered. They posited that this was the cause of reduced fluent reading skills.The study was led by Harvard Medical School professor Christopher A. Walsh, Beth Israel Deaconess...
Tsai has found that the deficiencies in p35 mice closely mimic those found in several human neural disorders, such as lissencephaly, which produces the same type of seizures found in the mice and periventricular heterotopia and double cortex--which are caused by incorrect migration of cortical neurons...
