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 center of mental activity. Aristotle, the philosopher of ancient Greece, thought that the mind was based in the heart.(71)
It was not until the 18 th century that man realized that the whole of the brain was involved in the workings of the mind.
During the 19th century scientists found that when certain parts of the brain were damaged, men lost the ability to do certain things. And so, people thought that each part of the brain controlled a different activity. But modern research has found that this is not so. It is not easy to say exactly what each part of the brain does.
In the past 50 years there has been a great increase in the amount of research being done on the brain.(72)
Chemists and biologists have found that the way the brain works is far more complicated than they had thought.
In fact, many people believe that we are only now really starting to learn the truth about how the human brain works. The more scientists find out, the more questions they are unable to answer. For instance, chemists have found that over 100,000 chemical reactions take place in the brain every second. Mathematicians who have tried to use computers to copy the way the brain works have found that even using the latest electronic equipment they would have to build a computer which weighed over 10,000 kilos. Some recent research also suggests that we remember everything that happens to us. We may not be able to recall this information, but it is all stored in our brains.
Scientists hope that if we can discover how the brain works, the better use we will be able to put it to. For example, how do we learn language? Some children learn to speak, read and write when they are very young compared to average children. But scientists are not sure why this happens. They are trying to find out whether there is something about the way we teach language to children which in fact prevents children from learning sooner.
