Quantum approaches have enormous explanatory power for understanding enigmatic features of consciousness. The Penrose-Hameroff ‘Orch OR’ model involves quantum superposition/computation in microtubules within the brain’s neurons. As technological quantum processes require extreme cold and isolation to avoid thermal decoherence, conventional wisdom holds against biological quantum processes in the apparently “warm, wet and noisy” brain. Methods which biological systems may have evolved to avoid decoherence are discussed.
