Human brain is very great.. sometimes we ourselves don't know it's potential....Last time when I was flippin my remote control of my TV.I happened to watch a program called "MY BRILLIANT BRAIN" at National Geographic Channel.
The program is all about the brilliance of Human Brain.Great scientist "ALBERT EINSTEIN" ,his brain is still preserved so that scientists can study his brain and try to find out whether his brilliance was god gifted i.e, by birth or was later developed through practice and study.

His brain was taken out of his body during his postmortem by the doctor and cut into 240 pieces which is still preserved till this day.
According to the program,his brain was different from normal brain.His brain was a little bit bigger.The gap at the temporal sides of the brain was merely seen, may be that was the reason he was so brilliant.
Doctors at the program stated that numbers of guinneal cells per neuron at the brain determines the brilliance of the brain and they discovered this by the experiment on rats.The rat that was kept in the cage where it was given toys to play with had more guinneal cells per neuron than the rat that was kept alone in a cage.
And the study of Sir Albert Einstein's brain also stated that his brain had more guinneal cells per neuron than a normal human being.
So, it is still a question whether brilliance can be gained by study and practice or it comes as god gift. But more or less it seems that brilliance of the brain is not acquired by anyone since birth from the view of the doctors and scientists today.
Sir Albert used to question himself like a kid and he tried to find the answer by himself until he got the answer.If we could do the same,we might discover many things as well...
