Series of complicated bio-electrical interactions?
Vast numbers of connections, neurons firing together?
Even our limited attempts at neural networks are not very well understood, and that is just code running on well understood computer. A brain is way more connected and complicated than something like deep mind, even if you think of that stuff like a first order approximation. So if we cant easily do that, seems an actual brain with way more recurrence and structure is much harder.
I think there are experimental results though, we can look at an brain scan and nearly deduce what people are looking at, although don't quote me I would have to find the paper. Seems pretty physical.
