Magnetic Resonance Imaging (MRI)
A non-invasive scanning technique that enables investigators to see and track Multiple Sclerosis (MS) lesions as they evolve. MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. MRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. MRI imaging is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called nuclear magnetic resonance imaging or NMRI.

Myelin
A fatty covering insulating nerve cell fibers in the brain and spinal cord, myelin facilitates the smooth, high-speed transmission of electrochemical messages between these components of the central nervous system and the rest of the body. In MS, myelin is damaged through a process known as demyelination, which results in distorted or blocked signals.

Myelin Basic Protein (MBP)
A major component of myelin. When myelin breakdown occurs, as in Multiple Sclerosis (MS), myelin basic protein (MBP) can often be found in abnormally high levels in the patient's cerebrospinal fluid. When injected into laboratory animals, myelin basic protein (MBP) induces experimental allergic encephalomyelitis, a chronic (lasting a long time) brain and spinal cord disease similar to Multiple Sclerosis (MS).

Myoclonus
Myoclonus describes a symptom and generally is not a diagnosis of a disease. It refers to sudden, involuntary jerking of a muscle or group of muscles. Myoclonic twitches or jerks usually are caused by sudden muscle contractions, called positive myoclonus, or by muscle relaxation, called negative myoclonus. More about Myoclonus
