Epilepsy. Artwork depicting an epileptic attack (or seizure) as lightning in the brain of a model head. Bolts of lightning (or electricity) are seen in the cerebrum, which is the largest and most highly developed part of the brain. Epileptic seizures are caused by abnormal electrical activity in the brain. The normally ordered electrical activity associated with brain function becomes chaotic and unregulated during a seizure. In some cases, a stimulus such as flashing lights can trigger an attack, but normally there is no apparent cause. Epilepsy is thought to be caused by disease or injury and may also be inherited.
