It's not even known how many kinds of cells there are in the brain. If you were looking for a periodic table of the brain, there is no such thing. I really like to think of the brain as a computer.

One of the things that got me transitioning from physical science to brain science was asking, Why do we understand so much about the universe?

Unlike optogenetics, where there are existing nonprofits that give away the DNA for free or at cost, expansion microscopy requires chemicals to be used, so having a company that makes the chemistry kit that anybody can use can save time.

We don't have a "consciousness meter" that'll tell us exactly how conscious something is. I think we might get there eventually.

Remember, when we're conscious of something, that state is quite often generated by unconscious processes that happen right before it.

If you give somebody a lot of questions to answer and then they walk by a bowl of candy, they are more likely to grab the candy because they're tired out from answering questions and can't resist.

I worry that we don't have a very good definition of consciousness yet which makes it hard to tackle.
