I don't think anyone's disputing that classical neural activity is primary. But the question quickly becomes: what decides and coordinates that neural activity?

I don't think anyone's disputing that classical neural activity is primary. But the question quickly becomes: what decides and coordinates that neural activity? It is it just an emergent effect of each neuron firing on instinct, producing an output for every input? Or is there some non-local coordination (quantum coherence) that calculates and ensures a correct firing sequence? Last I checked the evidence was pretty slim for the later. But it's not zero. (Check out Orchestrated Objective Reduction theory). We've seen quantum coherence in microtubules, during photosynthesis, and superradiance in proteins. But no direct evidence of non-local effects in a living brain. Yet.
