The interactive visualization is pretty great. Try zooming in on the slices and then scrolling up or down through the layers. Also try zooming in on the 3D model. Notice how hovering over any part of a neuron highlights all parts of that neuron:

My god. That is stunning.

To think that’s one single millimeter of our brain and look at all those connections.

Now I understand why crows can be so smart walnut sized brain be damned.

What an amazing thing brains are.

Possibly the most complex things in the universe.

Is it complex enough to understand itself though? Is that logically even possible?

I wonder if we manage to annotate this much level of detail about our brain, and then let (some variant of the current) models train on it, will those intrinsically end up generalizing a model for intelligence?

I think you would also need the epigenetic side, which is very poorly understood: https://www.universityofcalifornia.edu/news/biologists-trans...

We have more detail than this about the C. elegans nematode brain, yet we still no clue how nematode intelligence actually works.

Badly: https://www.lesswrong.com/posts/mHqQxwKuzZS69CXX5/whole-brai... (the comments have some updates as of 2023)

Almost every other cell in the worm can be simulated with known biophysics. But we don't have a clue how any individual nematode neuron actually works. I don't have the link but there are a few teams in China working on visualizing brain activity in living C. elegans, but it's difficult to get good measurements without affecting the behavior of the worm (e.g. reacting to the dye).
