What did the 19th century scientists think about our brain?
During the 19th century scientists thought that each part of our man’s brain does a different job. In the past fifty years there has been a great increase in the amount of research done on the brain. Scientists have discovered that the way the brain works is not so simple as people may think. Chemists tell us that 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happens to us. We may not be able to think back the things we’ve heard and seen, but it is all kept there in the storehouse of the human mind. Earlier scientists thought that power of one’s brain got weaker and weaker as one grew older. But it is now thought that that is not true. As long as the brain is given plenty of exercise it keeps its power. It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain. It is now thought that the more work we give our brains, the more work they are able to do.
