I'm a bit curious about the radio model. Where is the seat of consciousness?
If I hit my thumb with a hammer, I am aware of the injury, and the pain has a profoung effect on my behavior. But I can put aside pain if my survival depends on it. I can "objectify" my thumb and see it as something that is part of me but not mu central self.
I'm curious how the radio brain accounts for mind altering drugs. Why can't our real self see our addled brain as a disfunctional component that needs to be put aside for a while until it recovers?
It might be a 'whole is greater than the sum of its parts' kind of thing. It could be an aura around the entirety with no particular organ of its own. Replacng some parts wouldn't necessarily change the totality any more than changing violin strings or rehairing the bow would cause notes to be dropped from the music.
