Extended Data Fig. 10: Correlation between glomerular location and odor detecting properties.

a, Only glomeruli formed by OSNs expressing class II ORs were used for this analysis (N = 601). The data are presented as the mean with +/− bootstrapped 95% CI. Data were fitted with an exponential model (blue). OR proteins share substantial similarity with one another to facilitate common signaling pathways. The majority of the differences plotted here occur in the ligand binding regions of the ORs. b, The distribution of the glomeruli responding to the indicated ligands on the predicted glomerular map. The data presented in Fig. 4h are excluded here. c, Dendrogram of the OSN transcriptome. The coordinate of the predict glomerular positions on the A-P and D-V axis and the chemical responses to fatty acid odorants and ketones in Fig. 4h are indicated d, Volcano plot of the differentially expressed genes between OSNs that respond to the fatty acids and ketones indicated in Fig. 4h, the labeled genes are genes involved in lipid metabolism, two-sided likelihood-ratio test, Bonferroni correction for multiple comparisons.
