then arrival on two G-protein coupled receptors.

That's just the name they were given.

It's not a good name, I don't think.

There's not an H-protein coupled receptor that I know of.

But these G-protein coupled receptors are running this computation, super sophisticated computation, way better than what AI's got.

And that computation means I can play pool or I can learn to swim or I can learn to walk or I can speak French if I wanted to.

And the fact that these neurotransmitters are working together in consort is a surprise.

It seemed like they would likely do different things.

And my understanding of why we keep thinking that is because when I look inside my car, everything in the car has a different purpose.

The brakes have nothing to do with the transmission.

The transmission has nothing to do with power steering.

Power steering has nothing to do with the muffler.

That's because a human designed it.

And the way we think about things is to make one thing that does one job, one thing that does another job, one thing that does another job.

Biology, evolution is a tinkerer.

And it just makes up live and die.

Sometimes the wolf lives, sometimes the wolf doesn't live.

And we end up with this very messy thing

where all these pieces work together really well.

But when we try to give them labels, what is the thing that's causing Alzheimer's?
