Cortical dysplasia is a congenital abnormality where the neurons in an area of the brain failed to migrate in the proper formation in utero. Occasionally neurons will develop that are larger than normal in certain areas. This causes the signals sent through the neurons in these areas to misfire which sends an incorrect signal. It is commonly found near the cerebral cortex and is associated with seizures. Medication is used to treat the seizures that may arise due to cortical dysplasia.
