The present paper provides a selective overview of observations and questio ns stemming from the work introduced above in the Section Introduction by L udvigson. In addition, it explores certain theoretical issues and documents some uses to which odor-based responding has been put as an assay for drug effects, highlighting new data on aspartame.
