A microgyrus is an area of the cerebral cortex that includes only four cortical layers instead of six.
Microgyria are believed by some to be part of the genetic lack of prenatal development which is a 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 (Galaburda et al., 2006, Nature Neuroscience 9(10): 1213-1217). 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.

- Pharmaco-resistant epilepsies, and also some neuropsychiatric disorders, are often associated with malformations in hippocampal and neocortical structures. The mechanisms leading to these cortical malformations causing an imbalance between the excitatory and inhibitory system are largely unknown. An

- A variety of major developmental cortical malformations are closely associated with clinically intractable epilepsy. Pathophysiological aspects of one such disorder, human polymicrogyria, can be modeled by making neocortical freeze lesions (FL) in neonatal rodents, resulting in the formation of micr
