I thought this video was very interesting. People are self-aware, but where in the body does "i" live? Thats a question that people have been wondering for thousands of years. Marcus' s study covered a lot of different topics involving this question. He started by going to a doctor from Oxford who ran tests on his brain when he is under going sedation from anesthetics. He was told to imagine playing tennis while he is being injected with these imperative drugs. The doctor wanted to find the point where Marcus is still self-aware and he would b focusing on the area's of the brain that are still functioning under this heavy sedation. This, theoretically, should point us in the direction of which area of the brain our soul resides. They found that there is a "resonant loop" between the Thalamus and Basil Ganglia that is required to maintain consciousness. The doctor didn't say that this is where the consciousness resides, but it is one of the main components in being self-aware.
