Clear Messages in the Brain

Any kind of brain activity involves the passing on of signals from one nerve cell to the next. This can often result in up to 1,000 signals arriving at one single cell. In order to cope with these amounts, the brain features a well-thought out repression system. Scientists from the team around Prof. Dr Stefan Remy from the German Center for Neurodegenerative Diseases (DZNE) now have shown how this system works. "The system is like a filter, allowing only the most important impulses to pass", says Remy. In the case of patients suffering from Alzheimer's disease, this system is impaired.
