Summary of "Depth-dependent intracortical myelin organization in the living human brain determined by in vivo ultra-high field magnetic resonance imaging."

Intracortical myelin is a key determinant of neuronal synchrony and plasticity that underpin optimal brain function. Magnetic resonance imanging (MRI) facilitiates the examination of intracortical myelin but presents with methodological challenges. Here we describe a whole-brain approach for the in vivo investigation of intracortical myelin in the human brain using ultra-high field MRI.

Myelin Water Fraction Imaging Reveals Hemispheric Asymmetries in Human White Matter That Are Associated with Genetic Variation in PLP1.

Myelination of axons in the central nervous system is critical for human cognition and behavior. The predominant protein in myelin is proteolipid protein-making PLP1, the gene that encodes for proteol...

The identification and functional characterization of the repertoire of myelin proteins provides a valuable foundation for understanding molecular mechanisms of myelination and the pathogenesis of hum...

Myelin Plasticity and Nervous System Function.

Structural plasticity in the myelinated infrastructure of the nervous system has come to light. Although an innate program of myelin development proceeds independent of nervous system activity, a seco...

White matter intercompartmental water exchange rates determined from detailed modeling of the myelin sheath.

Magnetization exchange (ME) between hydrogen protons of water and large molecules (semisolids [SS]) in lipid bilayers is an important factor in MRI signal generation and can be exploited to study whit...

Experience-related reductions of myelin and axon diameter in adulthood.

The production of new myelin has been highlighted as an underappreciated mechanism of brain plasticity, but whether plastic decreases in myelin also happen in the adult brain is largely unexplored. Re...

Medical and Biotech [MESH] Definitions

Conditions characterized by loss or dysfunction of myelin (see MYELIN SHEATH) in the brain, spinal cord, or optic nerves secondary to autoimmune mediated processes. This may take the form of a humoral or cellular immune response directed toward myelin or OLIGODENDROGLIA associated autoantigens.

Proteins found in the myelin sheath. The major proteins of central nervous system myelin include: MYELIN PROTEOLIPID PROTEIN; MYELIN BASIC PROTEINS; and MYELIN-ASSOCIATED GLYCOPROTEIN. The major proteins of peripheral nervous system myelin include: MYELIN BASIC PROTEINS (myelin P1 protein and MYELIN P2 PROTEIN); MYELIN P0 PROTEIN; and MYELIN-ASSOCIATED GLYCOPROTEIN.

A high affinity receptor for myelin-associated inhibitors (MAIs) that include NOGO-A PROTEIN; OLIGODENDROCYTE MYELIN GLYCOPROTEIN; and MYELIN-ASSOCIATED GLYCOPROTEIN. It is expressed primarily by neurons in the brain and OLFACTORY BULBS. During embryonic development, it is expressed in the PERIPHERAL NERVOUS SYSTEM. It localizes to GROWTH CONES and may inhibit neurite outgrowth following SPINAL INJURY.

A myelin protein that is the major component of the organic solvent extractable lipoprotein complexes of whole brain. It has been the subject of much study because of its unusual physical properties. It remains soluble in chloroform even after essentially all of its bound lipids have been removed. (From Siegel et al., Basic Neurochemistry, 4th ed, p122)

A glycosylated extracellular myelin protein found on the MYELIN SHEATH of the CENTRAL NERVOUS SYSTEM. It is linked to the cell surface via a GLYCOSYLPHOSPHATIDYLINOSITOL LINKAGE.
