White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.
Condensed matter "computing substrate" that has the maximum computing power theoretically possible. [32] Some authors have speculated on the possibility of turning entire planets, or even the whole universe into computronium and what this would mean for humanity, or indeed, if humanity would even be needed after creating intelligences of such ...
The European Leukodystrophy Association also supports research into leukodystrophy. As of 2020, more than 387 research projects have been funded. Each year, ELA invites the international scientific community to submit research projects in the field of genetic leukodystrophies, the cerebral white matter in premature infants, and of myelin repair ...
Head CT showing periventricular white matter lesions. Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals, but sometimes in young adults. [1] [2] On MRI, leukoaraiosis changes appear as white matter hyperintensities (WMHs) in T2 FLAIR images.
Degenerate matter: Matter under very high pressure, supported by the Pauli exclusion principle. Electron-degenerate matter: Found inside white dwarf stars. Electrons remain bound to atoms but can transfer to adjacent atoms. Neutron-degenerate matter: Found in neutron stars.
White matter, primarily made up of myelinated axons Topics referred to by the same term This disambiguation page lists articles associated with the title Brain matter .
The gray matter remains normal in all characteristics while the white matter changes texture, becoming soft and gelatinous. Rarefaction of the white matter is seen through light microscopy and the small number of axons and U-fibers that were affected can also be seen. Numerous small cavities in the white matter are also apparent.
