Before revision:  This simple framework predicts receptor responses to mixtures of up to twelve monomolecular odorants to within 10-30\% of experimental observations and provides a powerful method for leveraging limited experimental data. Simple extensions of our model describe phenomena such as synergy, overshadowing, and inhibition, suggesting that these perceptual effects can arise partly from receptor binding properties, and may not require either complex neural interactions or feedback from higher brain areas.
