How about, it keeps the discussion moving:
”To see if they could show that the brain treats those two concepts differently too, Tallon-Baudryʼs team asked people who were having their brain scanned to fixate on a point and then let their mind wander. Every now and then, they were interrupted and asked whether – at that precise moment – they were thinking about “me” or “I”, which they had been trained to recognise. Depending on which they reported, the HEP occurred in different parts of the brain: a region near the front for “me” thoughts and one further back for “I” thoughts. This showed for the first time that the brain does indeed discern between the two concepts.” – Laura Spinney, “Consciousness Isn’t Just the Brain: the Body Shapes Your Sense of Self” at New Scientist
It shouldn’t be a big surprise if the brain distinguishes between the two concepts because subject (I, the person who makes things happen) and object (me, the person who experiences something) are more or less fundamental ideas.News, “The grammar of consciousness: I vs. me” at Mind Matters News
The mystery of consciousness includes our constant awareness of both of these statuses, I and me.
