A schematic illustrating the possible role of quantum effects in olfaction. Where previously olfaction has been proposed to depend on the shape and size of odourants fitting a specific receptor, experiments with fruit flies have indicated that the substitution of hydrogen with deuterium results in an odour change in spite of their having the same shape. This suggests that vibrational frequency might play a role in the detection of odourants [111].
