> Holding a donors brain in one's hand (it's smaller than one would expect). In the words of a lab partner, "I can't believe we are holding everything that made this person a person, all their personality, everything."
Thought provoking. I'll keep this in mind while holding a hundred billion apples during lunch. ;)
From another angle, I would argue that the eyes and face are part of what makes a human, as are the hands. And there's also something in the brain that has been lost, something beyond mere physical matter. An easy example of this is a puzzle, if you're putting a puzzle together, and I come in and mix it up, I've taken something from you, and yet I took no material object away. There's probably some organization that's part of our brain and "humanity" that is lost at death. I'm not talking about religious "spirit" here - back to the puzzle, it has no spirit, but an assembled puzzle is more than the physical material it is made of.
I don't mean to be super critical of your lab partner, just sharing some additional philosophical views.

I also agree with this take, though in the moment at the lab I didn't interject with a critique of mind-body dualism. Either way, it seems the brain has some sort of primacy over other organs, in terms of contributing to personhood. Pretty much everything else could be lost or transplanted, yet we'd still consider someone the same person. The brain however seems essential in making you you.
A large amount of computation takes place in the gut, largely by the foreign bacteria that make up our gut flora, and the gut has direct lines of two-way communication with the brain. Hence the term "gut feeling".
The brain certainly does a lot of heavy lifting, but I think if you took a person's brain out of their human body and into a robot body instead, they'd probably have dramatic shifts in personality, behavior, thought processes, feelings, worldview, etc. It would probably be on a similar level as those experiments where people use magnetic or electric pulses on their brain or whatever and observe large personality changes.
