There is a really good lecture on finding out about the brain and cool stuff about it in this video: http://www.ted.com/talks/view/id/184
The neurologist Vilayanur Ramachandran explains how scientists can find out more about the brain by looking inside of brains that is not normal or injured. In it, he examines three oddities: People who can’t recognize faces or recognize faces but thinks the person is a stranger, phantom limbs (people can feel their limbs even though it is cut off), and synesthesia (the mixing of senses, like certain numbers make people see certain colors). In it, he explains why he thinks those things happens and gives you insight of the inner workings of the brain, and how he finds about it. I especially like the part of synesthesia, sounds like a cool thing to have 🙂 . Oh, and anyone reading this should check out other TED lectures, K?
