Well, I strongly recommend that you can take a look at the links Lemon Koala provided. As her classmate this semester in bio lab, I was quite shock when Wil showed us that how untrustable our brain is.

But anyway, we have to trust our brain. Rather say it is a betrayal, I believe in the good side of the brain: It is protecting us. Although the brain doesn't let us know its true color, it does things that truely help us understand the world in a more perceivable way. There are too many infomation for the brain to take care, and if the burden is on our shoulder, there is no guarantee that we can sit here and focus on one topic named "brain". At one sight, your eyes see a laptop, your tapping hands, a bright lamp, bunches of notebooks of different color, several pens.......If you are the one to deal with the high-throughput messages every second, you are going crazy. When the brain feels the danger, it sends signals to us as warning sign.

But on the other hand, when the brain stop functioning well, we have to know what's happening inside. Also, we want to know if we can trust our intuition, since we are not  the main characters of TV shows who know exactly what to do in the nick of time. Does the "betrayal" of brain mean that I, a complete soul as I understand, am just a part of my body which is not that intelligent who is in charge of the thinking part of my body? All the features that we can't control are called human nature, but where do they come from? What if we can switch on and off our ability to understand every dicision of our brain, will us be a super monster computer who is too well to analyze everything rationally and intelligently that we may lose our nature and emotions?
