| 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? Man differs most from all the other animals in his ability to learn and use language but we still do not know exactly how this is done. Some children learn to speak and 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. Earlier scientists thought that during a man's lifetime the power of his brain decreased. But it is now thought that this is not so. As long as the brain is given plenty of exercise it keeps its power. It has been found that an old person who has always been mentally active has a quicker mind than a young person who has done only physical work. It is now thought that the more work we give our brains, the more work they are able to do. They say that the only limit on the power of the brain is the limit of what we think is possible. This is probably because of the way we are taught as children. When we first start learning to use our minds we are told what to do, for example, to remember certain facts, but we are not taught how our memory works and how to make that best use of it. We are told to make noted hut we are not taught how our brains accept information and which is the best way to organise the information we want our brains to accept. This century man has made many discoveries about the universe -- the world outside himself. But he has also started to look into the workings of that other universe which is inside himself -- the human brain. |
