computer The human brain has been called the world's most
complex computer. It's abilities come from a complex circuitry of
billions of neurons. There are three main parts to the brain: the

coordinates balance and movement; and the "cerebrum", which is
responsible for all conscious experience, like thought and
feelings. The cerebrum is the largest part of the brain. 14 APRIL 2000
