Cliff notes: the brain is quantum in nature and the quantum processing is done by microtubules not neurons. You consciousness is sort of created by the entanglements with in the microtubules. Mind blowing part... when you die your consciousness may hang around on the quantum entangled information metalayer of the universe which fits with holographic theory and stuff like that.
Cliff notes 2: if you use exciting sciency concepts like Quantum, entanglement and microtubules people will miss the fact you are spouting mumbo-jumbo
