In the matter of its own special activities, the brain is usually undisciplined and unreliable. We never know what it will do next. Arnold Bennett.

Despite the enormous capacity of the human brain, we only utilise on average less than three percent of our potential brainpower. This is the amount of information available to us consciously, and the rest is locked within our subconscious mind. There is, therefore, the potential for each of us to expand our brainpower considerably.

I am a great believer that by regular practise on different types of tests and puzzles each one of us has the capacity to increase our brainpower and strengthen our performance at different types of brain activity such as creative thinking, problem solving, memory, logical thought and mental agility in the same way that gymnasts are able to improve their performance, and increase their chances of success, at whatever level they are competing, by means of punishing training schedules and refinement of technique.

Many of us take our brain for granted, believing there is little we can do to improve the brain we have been born with. Also, because we know so little about the human brain, there is the fear factor - the fear of the unknown that we do not even like to think about, let alone talk about - however, the brain is the most vital organ in the human body and our most valuable asset. It gives rise to our perceptions and memory, and it shapes our speech, skills, thoughts and feelings, yet it is perhaps the part of or body which we tend to neglect the most.

In the past few decades we have become much more aware of the importance of the human brain , its functioning and its relationship to our body, in fact we have learned more about the brain in the past decade or so than in all of the previous centuries.

About the Brain
|
|
The studying of other animals suggests a relationship exists between brain size and intelligence levels. The dolphin, for example, has an unusually large brain and is considered one of our planet’s most highly intelligent creatures. Human brain size levelled off about 100 thousand years ago. Unlike animals, there is no relationship between brain size and intelligence level in humans.

When it comes to human brain size, therefore, bigger is not necessarily better. In fact, scientists believe bigger could be worse, because increased size may impede rapid communication between nerve cells within the brain. In vertebrates the brain is the portion of the central nervous system within the skull. Often referred to as grey matter it is, in humans, a mass of pink-grey tissue and weighs approximately 1.3 kg (3 lb).
