It's definitely along these lines. Like so much (everything?) that is us happens amongst this tiny little mesh of connections. It's just eerie, isn't it?
Sorry for the mundane, slightly off-topic question. This is far outside my areas of knowledge, but I thought I'd ask anyhow. :)
That said I do get this eerie void feeling from the image. My first thought was to marvel how this is what I am as a conscious being in terms of my "implementation", and it is a mess of fibers locked away in the complete darkness of my skull.
There is also the morose feeling from knowing that any image of human brain tissue was once a person with a life and experiences. It is your living brain looking at a dead brain.
I'd be much more horrified to see our consciousness simplified to anything smaller than that, which is why any hype for AGI because we invented chatbots is absolutely laughable to me. We just invented the wheel and now hope to drive straight to the Moon.
Anyway, you are seeing a fake three dimensional simplification of a four+ dimensional quantum system. There is at least one unseen physical dimension in which to encode your "soul"
If the wires make consciousness then there is consciousness. The substrate is irrelevant and has no bearing on the awesomeness of the phenomena of knowing, experiencing and living.
