Crazy Brain

There is always a contrary in the mankind about who rules them. This question was there for centuries. And I say man who says "I have found the one which control all our life", have never seen the truth. Scientist and Doctors believes that human activities are controlled by Brain. And they form lot of stories to make their words true.
Lot of documentary movies and lot of magazines tell lot of things about brain. And I don't want to spoil their belief. Whatever they found are true and they have hidden other things they have found out. Unfortunately people are running after money and if they are telling the truth then they will be losing their money. People will be educated with right knowledge and won’t go behind doctor’s word. So doctors speak the words that make them money.
Brain gives signal to all part of our body and controls all our action. But where does the idea of doing certain things come from? The choices we make in our life decide who we are going to be in life? And we don't know where it will end when we make that decision. Where do these thought come from? - Brain. No I think, if it is from brain then it should know the end point of its action.
I was watching a documentary on brain last week. There they were showing women whose brain is operated while she was conscious. They found which part of the brain was controlling the speech process. The doctor asks the patient to count from 1 to 10 and back to 1. The patient was doing the same meanwhile the doctor places an electrode on the part which controls the speech. When electrode was toughing her brain she was not able to pronounce. But she was able to think about the number. What makes her think? Do research on this and tell me.
