I followed your links and ended up in this rather excellent essay:

One of the final points the author makes is that the brain might be a neural network made up of as many as 89 million neural networks.

That's a staggering concept.

If true, I wonder how anyone stays sane with that level of entropy in the system!

The "neural network of neural networks" thing is a bit of lavish exaggeration TBH, because a network of networks is just a larger network. The human brain has about 100tn synapses, which I think is a less obscure statistic to marvel about.
