In game theory, the Nash equilibrium is a solution concept of a non-cooperative game involving two or more players in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only his own strategy.[1] If each player has chosen a strategy and no player can benefit by changing ...
Myelinated nerve fibers occur predominantly in the cranial and spinal nerves and compose the white matter of the brain and spinal cord. It is the myelin sheath that gives the whitish color to the areas of white matter. Unmyelinated fibers are abundant in the autonomic nervous system.
Myelination consists of multiple layers of the cell membrane of either oligodendrocytes or Schwann cells (neurolemmocytes) wrapped around the axons of neurons. The cell membrane wrapping is called myelin. A number of glial cells are necessary to form the myelination along the length of an axon.
