Brain microtubules alone are not the source of quantum consciousness, as suggested by Hameroff and Penrose, but are channels for quantum coherent water nanocluster terahertz vibrations that produce by interference the much lower beat frequencies observed in EEG brain scans. These beat frequencies correspond to discrete thoughts and self-awareness.

Wonderful ties Hameroff with Damasio well they are both Nobel Prize worthy
