Epileptic fits are like thunderstorms raging in the brain: Nerve cells excite each other in an uncontrolled way so that strong, rhythmic electrical discharges sweep over whole brain regions. In the wake of such a seizure, the nerve cells are severely affected, and permanent damage is possible. The glia, a class of cells that surround the neurons in the brain, was long suspected to contribute to the damaging effects of epilepsy. Quite the opposite is the case, as the team of Prof. Dr. Carola Haas from the Bernstein Center and Dr. Matthias Kirsch from the Institute of Anatomy and Cell Biology at the University of Freiburg shows for the first time.
