Our brain is mainly divided into 2 "halves", the left side and the right side. The left-hand side is seemingly responsible for number and language. It is likely to process information logically. However, the right-hand side of the brain takes a more holistic view of information and enjoys patterns. When we are thinking laterally, it is probably involved also. Not surprisingly, the right side is known as the more creative half of the brain. Generally, men tend to be left-brained and women are to be right-brained. This kind of generalization needs to be treated with concern.

It is discovered that the corpus callosum (the part of the brain connecting the 2 halves) is somewhat thicker in people whose right side of the brain is dominant. People who understand their creativity fully are those who can use both sides of their brain most efficiently. Our brain tends to organize things into familiar patterns and our mind seeks to make connections to things it already "knows" and then "stores" the experiences accordingly. This can be unhelpful when you are trying to be creative. About 30 years ago, Edward de Bono observed that: Insight, creativity and humor are so exclusive because the mind is so efficient. The mind functions to create patterns out of its surroundings. As the patterns are used they become ever more firmly established.
