Microstructures in the Living Brain: Magnetic Resonance Imaging of the Myelin Sheath
Research report (imported) 2009 - Max Planck Institute for Human Cognitive and Brain Sciences
Nerve fibers of vertebrates are enveloped by a lamellar membrane sheath referred to as myelin. Myelin acts as an electrical insulator and is of fundamental importance for the nerve conduction. By use of relaxographic magnetic resonance imaging, it is feasible to obtain spatial information about the myelin sheath through the observation of intercalated water molecules. This leads to a novel modality for microstructural investigations of the living brain.
