Figure 4. Glomerular activation versus vibrational spectra similarity.

Figure 4

Euclidean distances of the average odorant response maps between pairs of isotopomers are plotted against their differences in spectral overlap in the spectral window of 2000–3300 cm−1. Odorant abbreviations are 1-octanol: OCT; benzaldehyde: BZA; acetophenone: ACP; isoamyl acetate: ISO.
