There is little doubt that faster and more efficient processing in the brain will help a person to perform better and achieve more. But is it possible to change how the brain processes information?
It is the left side of our brain that ensures that we understand language and produce speech, but it is the right side of our brain that looks after the intonation of our speech. This was discovered around 150 years ago, when doctors noticed that patients with a stroke on the left side of the brain often lost speech, and that those with a stroke on the right side mostly spoke in a monotonous voice, without any intonation, rhythm or stress.
The adult brain of a human weighs about 1.4 kg (3 pounds), and in relation to the size of our body, is much bigger than what would be expected compared with other creatures. This large size does pose special problems for an effective communication between the two sides of the brain and this is probably the reason why specialised centres for specific processes developed in the human brain.
