Why does the brain require such a large percentage of the body's total blood flow?

The brain contains billions of neurons (nerve cells) which are constantly sending signals to each other and to the rest of the body, whether you're awake or asleep. The neurons send their signals by pumping ions into and out of themselves, which takes energy. Each neuron has millions or billions of ion pumps, so even though a single ion pump doesn't use much energy, all the ion pumps in a neuron multiplied over the billions of neurons in the brain require substantial energy to operate. The blood that travels to the brain delivers the oxygen and glucose necessary for the brain to maintain these activities.
