Seven Myths about our Brain ....


1. We use only 10% of our brain

That is untrue. PET scans of the brain show that much of the brain is active. From an evolutionary point of view it does not make sense for the brain to develop 90% of useless brain either. It is established and proven that we use 100% of our brain, but not all of it at the same time, we use different parts for different reasons but overall the whole brain is used. Therefore do not be tricked by those adverts offering to tap into your unused brain power as you probably don’t have such a thing as unused brain.

2. When brain cells die they cannot be repaired.

Recent research has identified techniques for “growing” new brain cells when old ones are damaged

3. Our brain is like a computer.

That is untrue, first of all computers are digital while our brain is analogues, as the phone or telegraph, second our brain is much more complex then a computer, until molecular computers (and there are hopes) or some other device of that sort are developed comparing our brain to a computer is an oversimplification and an insult to the beautiful machine nature has given us.

4. The blanket-slate myth

This is the myth that the brain is like a clean blanket ready to be furnished. This is untrue also as genetics has a role to play in the formation and operation of our brain, nonetheless the environment has a great role to play also, genetics and environment perform and intertwined dance in the development and growth of our brain.

5. The brain matures by the age of 5

Much of the brain growth and reorganisation occurs between the ages of 5 to 20 but the brain has the capacity to grow throughout life.

6. The sponge myth

The sponge myth suggests that the brain can absorb so much information, when it’s full it’s full and the brain learn just by exposure to the world, therefore it is passive in its learning.
Both of the suggestions are untrue, it appears that the brains capacity to learn seems almost limitless, what limits it are only the priorities and motivations of the learner. Learning is a very active process which requires doing something on the part of the learner which might be just imagining something. The brain is its own teacher.

7. The mediation myth

Some believe that the brain learns better when relaxed which is why some buy a tape recorder and play it during sleep. Psychological experiments have shown that this is untrue, further the brain learns best in a state of arousal as you are focused.
