First of all - How does on control indeterminism? And does QM indeterminism really play a role on a neuronal level?

That said, most attempts at quantifying whether or not distinctly quantum mechanical processes in the brain related to things like microtubules and NMDA receptors are significant to cognition (i.e. is the brain a quantum computer?) have generally concluded the answer is no: See: https://arxiv.org/abs/quant-ph/9907009 https://onlinelibrary.wiley.com/doi/pdf/10.1207/s15516709cog...&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/quant-ph_9907009/"&gt;Paper and discussion history&lt;/a&gt;.

Maybe the simulation algorithm is the thing that needs improvement.

Basically, Penrose assumes that: 1. Gödel&amp;#x27;s Incompleteness Theorems are equivalent to the halting problem (provable) 2. If the human mind is deterministic, it can be modeled with a deterministic algorithm (provable). 3. The human mind seems to be capable of proving arbitrary things about all algorithms (debatable; I&amp;#x27;m extremely skeptical). 4. Therefore, the human mind is not bound by the halting theorem, and therefore the human mind is not deterministic. He then draws several possible speculations. 1, the human mind is driven by quantum…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/quant-ph_9907009/"&gt;Paper and discussion history&lt;/a&gt;.
