The responses of a population of 30 olfactory receptor cells from spiny lobsters to 8 behaviorally relevant complex types of stimuli at 0.005, 0.05 and 0.5 mMwere analyzed using multidimensional scaling to evaluate their potential for coding quality and intensity. A discrimination index was derived from the resulting stimulus coordinates, which takes into account the response similarities within type/concentration and the response dissimilarities between types/concentrations. The results indicate that quality and intensity can be discriminated by separate components of the response of the population of neurons: quality by the pattern of responses produced across the neuronal population, and intensity by the absolute response magnitude.
