There is only limited exchange between the blood and cerebrospinal fluid. This so-called blood-brain barrier acts as a filter that allows the necessary substances such as oxygen, carbon and water to pass through and keeps harmful substances away from the nervous system. However, some diseases and influences such as electromagnetic radiation may interfere with the function of this barrier.
