Left brain and right brain comparison

The part of the brain that controls rational functions (cerebral cortex) is made up of two halves, left brain and right brain. They are connected to each other by a thick cable of nerves at the base of each brain which is called the corpus collosum. The corpus collosum allow messages'to pass between these two brain. You can think of it as an Ethernet cable or network connection between two giant processors, each running different programs from the same input.

For some reason, our left and right brain control the opposite side of our bodies so the right brain controls our left side and processes what we see in our left eye while the left brain controls the right side and processes what our right eye sees.

These two brain has different ways of thinking. The left brain is verbal and processes information in an analytical and sequential way, looking first at the pieces then putting them together to get the whole.  Our logic and reasoning skills come from this half as do number skills. We use this side of brain to recognising friend's face in a crowd or lining up words to make a sentence.

By contrast, the right brain is visual and processes information in an intuitive and simultaneous way, concentrated on the broad and background picture then the details. The researchers believed it had a panoramic focus that made it good at seeing general connections. The right side is where spatial imagery comes from.  Art appreciation comes from this half. This hemisphere was best able to represent the relative position of objects in space and to handle the emotional and metaphorical aspects of speech.

In a neat and complementary division of labour, one side of the brain thought and saw in wide-angle while the other zoomed in on the detail. Our personality can be thought of as a result of the degree to which these left and right brains interact. It is a simplification to identify left brain types who are very analytical and orderly. We likewise certainly know of the artistic, unpredictability and creativity of right brain types.  As people get older, they use one side more than the other half.

So, is it better to be right brained or left brained? Though right brain or non-verbal thinking is often regarded as more creative, there is no right or wrong here. It is merely two different ways of thinking. One is not better than the other because each side has its own function and responsibilities. What's important is to be aware that there are different ways of thinking, knowing your natural preference is. If it is strongly verbal (left brain) rather than visual (right brain), being open to trying new approaches which deliberately approach painting or drawing in a right brain way.  Research into the operation of the right and left hemispheres shows that the effective processing of information requires access to both as they complement each other.
