Where does consciousness reside "what makes you, you" self-awareness has always been an interest of mind. The idea of consciousness amazes me, how does it happen?
Why is it unique to everyone? And where does it reside? Marcus de Sautoy and BBC's The Secret You did a wonderful job asking these questions and showing us the modern approaches we use to solve these big questions. The Secret You tries to explain where consciousness resides and explains that the cortex, located on the outer part of the brain, allows us to be self-aware. 
This self-awareness comes from nerve cells in the brainstem sending projections from the thalamus out to all areas of the cortex; this constant "Activeness" is part of what makes us aware. As far as evidence the show did a great job because they had and actual brain which was really interesting to see. But after hearing these origins of consciousness I began to wonder about situations where these origins are disrupted by either disease or accidents. There are cases where people are unconsciousness for extended periods of time wake up and are back to themselves in no time, but in other cases people can loose all self-awareness. I've attached a very interesting case of Dissociative amnesia where a woman lost all sense of self-awareness for 10 months and then all of a sudden had it trigged and for the most part returned to her normal self. Cases like these amaze me and I hope to see more scientific breakthroughs in understanding the brain in the future.
