[HTML][HTML] Functional regeneration of the brain: white matter matters
In the human brain, white matter makes up about 50% of the brain volume and consumes
43.8% of the brain's total energy budget for resting potential maintenance (Harris and
Attwell, 2012). Composed of primarily myelinated axons, the white matter is the “highways
and subways of the brain” connecting one region to another and trafficking in and out of the
grey matter. In the myelinated nerve fibers, layers of myelin sheaths wrap around each axon
to provide protection and insulation to the axon and to allow rapid conduction of action …
