Brain cell.

Every cell in a human brain contains the same sequence of DNA, but in different cell types different genes are copied onto strands of RNA for use as protein blueprints. This ultimate variation in which proteins are found in which cells—and at what levels—allows the vast diversity in types of brain cells and the complexity of the brain. Brain Cell. When adaptation of brain cells has already occurred, however, a rapid rise in serum sodium concentration may induce a shift of water from the ICF to the ECF compartment, resulting in brain dehydration and subsequent brain injury, that is, the osmotic demyelination syndrome.
