Neurons spiking is a lot of quantum woo, as you put it. Collapse of an electric charge gradient across a membrane, neurotransmitters being released and binding to receptors, etc., all involve various QM processes. I was however thinking more about photon scattering, reflection, and emission from so-called material objects, well before those photons hit the rods and cones in the eye.
