White matter lies beneath the grey matter cortex in the deeper tissues of the brain and so is referred to as subcortical. It constitutes millions of bundles known as either axons or nerve fibres. These are extensions of nerve cells called neurons which are connected by the axons across different brain regions into functional circuits. Axons are coated in an electrical insulation substance called myelin, which gives the white matter surface its colour.
