That’s why consciousness is “magical,” still. If neurons ultra-basically do IF logic, how does that become consciousness?
And the same with memory. It can seem to boil down to one memory cell reacting to a specific input. So the idea is called “the grandmother cell.” Is there just 1 cell that holds the memory of your grandmother? If that one cell gets damaged/dies, do you lose memory of your grandmother?
And ultimately, if thinking is just IF logic, does that mean every decision and thought is predetermined and can be computed, given a big enough computer and the all the exact starting values?
Individual cells do not encode any memory. Thinking and memory stem from the great variety and combinational complexity of synaptic interlinks between neurons. Certain “circuit” paths are reinforced over time as they are used. The computation itself (thinking, recalling) then is “just” incredibly complex statistics over millions of synapses. And the most awesome thing is that all this happens through chemical reaction chains catalysed by an enormous variety of enzymes and other proteins, and through electrostatic interactions that primarily involve sodium ions!
Seth Anil has interesting lectures on consciousness, specifically on the predictive processing theory. Under this view the brain essentially simulates reality as a sort of prediction, this simulated model is what we, subjectively, then perceive as consciousness.
“Every good regulator of a system must be a model of that system“. In other words consciousness might exist because to regulate our bodies and execute different actions we must have an internal model of ourselves as well as ourselves in the world.
As for determinism - the idea of libertarian free will is not really seriously entertained by philosophy these days. The main question is if there is any inkling of free will to cling to (compatibilism), but, generally, it is more likely than not that our consciousness is deterministic.
Its not that odd if you think about it. Everything else in this universe is deterministic. Well, quantum mechanics, as we observe it, is probabilistic, but still governed by rules and calculable, thus predictable (I also believe it is, in some sense, deterministic). For there to be free will, we need some form of “special sauce”, yet to be uncovered, that would grant us the freedom and agency to act outside of these laws.
True.

Interesting about moving towards consciousness being deterministic.
(I haven’t been keeping up with that)
