The human brain is a truly incredible instrument, faster than the fastest super computer. It receives millions upon millions of impulses per second from all your senses, and it computes all of them to make sense out of the world around us.  But, there is a problem. As every computer user knows, if your input is muddled, the output will also be muddled. The same happens with the human brain. Sometimes, what the eye sees is not what the brain perceives.

Before we get to the serious business, let me give you some brain 'confusers' and some brain 'teasers'

No 1

                                                                    How many legs does this elephant have?
No 2

                          Is this image really moving?
No 3

Look at the chart and say THE COLOUR, not the word!
This is LEFT-RIGHT conflict.
Your right brain tries to say the colour, your left brain tries to say the word.

No 4

Your brain sometimes 'completes'
a picture, like this one.
What do you see?

Some people will see an E, others
just the lines.

No 5

The next is well known. What do you see?
Can you see the young man and the old man?
Do you only see one, or both?

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.
