Microgyrus

Microgyria are believed by some to be the cause of, or one of the causes of, dyslexia.

Albert Galaburda[?] of Harvard Medical School[?] noticed that language centers in dyslexic brains showed microscopic flaws known as ectopias and microgyria. Both affect the normal six-layer structure of the cortex. These flaws affect connectivity and functionality of the cortex in critical areas related to sound and visual processing[?]. These and similar structural abnormalities may be the basis of the inevitable and hard to overcome difficulty in reading.
