Random one today...
Epilepsy is a medical condition that produces seizures. A seizure happens when a sudden increase of electrical activity interferes with normal operations in the brain.
Nerve cells use electrical particles to communicate with each other. Millions of electrical particles pass between nerve cells in the brain. When the brain has a sudden burst of electricity, the body experiences physical changes called epileptic seizures. Victims can shake uncontrollably for brief periods. They also can temporarily lose the ability to think clearly or communicate.
New research is helping to explain how cells communicate to cause conditions like epilepsy. Douglas Fields is a researcher with America's National Institutes of Health. Two years ago, he showed that a chemical called ATP could be linked to disorders like epilepsy and chronic pain.
