Why does the brain need a continuous supply of glucose?

• Glucose stores in the brain are located behind the blood–brain barrier and are inaccessible to the brain cells.

• Glucose is exchanged very slowly between the blood and the brain cells, so a continuous supply is needed.

• The quantities of glycogen stored in the brain are not sufficient for the brain’s energy requirements.

• High glucose levels in the brain impair its function.
