Odorant mixtures elicit less variable and faster responses than pure odorants - Fig 6

(a) Comparison between cross-concentration correlations of ORN response patterns for mixtures with their components under various ratios, computed using our receptor model. The size of the mixture effects will decrease smoothly as the ratio of components becomes more unbalanced, but the mixture effects can still be observed when the composition of the mixture is highly unbalanced (dark green). In addition, the mixture effects can still be observed even when considering previous models [7]. (b) Cross-concentration correlations of ORN response patterns and (c) first-spike latency for mixtures and single odorants when considering a previous model [7]. The mixture effects described in the main text can still be observed: Latency is shorter and cross-concentration correlations is higher as the no of components in the mixtures increase. Please refer to Fig 3b (bottom panel) and Fig 4a for a direct comparison with the results of our receptor models.
