Tetragrammaton. fundamentally your brain is where all the action is happening it's the densest representation of you in the body

and the reason we know this is because if you were to damage part of one of your other organs,

like your heart or your lung or your spleen or your kidney, you know, you might have some

problems as a result of it, but it can get fixed. And in fact, the heart can get replaced

entirely. You can put in an artificial heart, you know, and they have these pulseless hearts

that just are machines that run the blood through. You don't even pulse anymore. And yet, you're the same

person. But if you damage even a very tiny chunk of brain tissue, that changes who you are. That

changes your hopes and dreams and aspirations and your capabilities and your ability to recognize animals

or see colors or understand mirrors or listen to music or hundreds of other things that we see

in the clinics every day and that's how we know that the brain is the important dense three

pound representation of you much more than the other organs.

So the way I think about it is the brain is sort of like the city center.

And yes, there's this communication to the outlying areas,

but the city center is sort of where all the action is happening.

There are stories of people who have heart transplants and then their emotional lives

changed.

There are stories like that and I interpret them to be romantic stories. And again, the reason

we know that is because thousands of people get artificial hearts or heart transplants every single year and they're the same person.

Obviously, going through a major surgery like that can change you and make you appreciate life in a different way.

So you might come out feeling a little different on the other side, but not because it's a different heart.

Explain your theory on why we dream.

Okay, so it turns out the brain has to take care of all these
