The Brain--The Most Powerful Computer in the Universe
Throughout the ages different ideas have been expressed about the workings of the human brain. It is only recently, however, that science has begun to give us some idea of how the brain really works.
Man still has a lot to learn about the most powerful and complex part of his body—the brain. In ancient times men did not think that the brain was the centre of mental activity. Aristotle the philosopher of ancient Greece thought that the mind was based in the heart. It was not until the 18th century that man realised that the whole of the brain was involved in the workings of the mind.
