It not clear to me how well that maps onto LLMs. Our wetware predates language, and isn't derived from it. Language is built on top. LLMs are derived from language. I think that means that the intermediate layers are very different from the brain neurons, but I don't know. It's eerie how well the former emulates the latter.
Even more interesting, and getting off on a bit of a tangent, there is also a mode that I use for revealing emotions that I don’t have words for (alexythmia): I open up a text editor, stare off into space, and let my fingers type without “observing” the stream of words coming out. I then go back and read what I “wrote” and often end up understanding how I’m feeling much better than I did. It’s weird.
Edit: also, playing with local models through e.g. llama-cpp in “thinking mode” is super fascinating for me. The “thought process” that comes out before the real answer often feels pretty familiar when I reflect on my own inner monologue, although sometimes it’s frustrating for me because I see where their “thinking” went off the rails and want to correct it.
