2 Figure 1 The Sparse Representation of Natural Scents
Natural odorant stimuli, such as those provided by food or drinks, are composed of hundreds of individual chemical components. The recording of glomerular activity in the olfactory bulb of animals stimulated by natural odors shows that the representation of complex scents involves only few glomeruli per odor. In their study, Lin et al. show that this spare representation results from the activity of few salient chemical features present at low concentrations in complex natural odor signals.
