#2Funny, it looks about as complicated as I would have imagined it.

#3Just wondering...
How complicated does a brain have to become in order to understand itself?
Could a brain exist that is so complicated that it could not understand itself, or does a brain's understanding always scale up with its complexity?

That very much depends on whether the complexity increases intelligence/comprehension or whether it is merely increased complexity.

Technically, considering a long enough timescale, a brain is the Universe trying to understand itself.

Right.. There are brains larger than ours with less intelligence.

You should first define what actually means "understanding the brain" before you try to answer this question.
Does "understanding of the brain" mean, that we can construct or simulate a brain? An artificial brain, which reproduce our intelligence and consciousness?
There is no reason to believe, that we can't do this. A brain is part of our world, governed by physics.
However, we will never be able to understand the thought process down to each individual activation of the neuron.
That's like trying to "understand" and follow the movement of each atom in my coffee next to me.

Re: What the brain's wiring looks like
#9Looks like any MRI. I did this from scans of my brain and than tried to follow the visual cortext to my eyes. I couldn't, because the scans only show the general direction water flows in, but the nerves behind the eye cross and at this point you can't tell what is just noise and what are interlaced nerves.
Would be interesting to know how much better this model is.

#10> The scan shows fibres in the brain's white matter, called axons
No. It shows the general direction of water molecules moving (mostly) outside those fibres. The end image is the result of some statistical processing of those vectors and some interpolation between "slices".
So what we see has been influenced by fibres, but it's not actual fibres. It is very likely that much of the detail and branching was lost in the process.
