Is the Brain a Quantum Computer?

After the mildly clickbaity title, I have to start out with some honesty: we don’t really know if the brain is a quantum computer or not.

But as with many a question we don’t know the answer to, thinking about them can still be worthwhile in their own right. And I believe there are good arguments indicating that the brain isn’t a quantum computer, so the answer is more like we don’t know, but probably not.
