Comparison of odor responses between PNs and OSNs. a The summary of odor response intensity of 31 PN classes to 17 odors. Spike frequencies during a 1-s odor stimulation period are color coded. b Histograms of PN response intensity. The histogram is accumulated across all 527 PN-odor pair response magnitudes (31 PN classes × 17 odors). c The summary of odor response intensity of 29 OSN classes to 17 odors recorded by single sensillum recordings. Spike frequencies during a 1-s odor stimulation period are color coded. d Histograms of OSN response intensity. The histogram is accumulated across all 493 OSN-odor pair response magnitudes (29 OSN classes × 17 odors). e Pearson's correlation coefficient between PN and OSN odor response intensities compared for each of 29 glomeruli. f The same values of Pearson's correlation coefficient as in e are mapped on the 29 glomeruli in a template AL
