Relative similarities in spatial patterns of glomerular layer activity are predictive of relative similarities in odors perceived by rats. Patterns of activity were measured using 2DG uptake, and perceptual similarities were measured using a five-odorant confusion matrix [4]. Relationships among both the patterns and the perceptions were visualized using multidimensional scaling. The perceptual data were reliably predictive across five separate animals as indicated by the standard errors. This figure is modified from [4]
