Scientists find just how discriminating a worm can be: Unique system of overlapping odor sensors discovered
...cause it displays many developmental processes and instinctive
behaviors common to higher organisms. The worm is tiny and transparent, with a very small brain that can be studied in detail. The key odors of interest in the UCSF study were benzaldehyde, which gives off a scent somewhat like almond, and butanone ...
Both smells and pheromones may arouse instinctive behaviors in mammals

drives, neuroendocrine responses and innate behaviors. The findings by Novotny and his collaborators demonstrate that the VNO and OE do not, in fact, detect mutually exclusive sets of chemicals. Novotny's laboratory identified the first definitive ma...
