... been identified. By using a combined gas chromatographic—single receptor neurone recording technique (GC—SC), we set out to identify active odour molecules in head space-collected volatiles from preferred food sources, i.e. different overripe or rotting fruit. In total, we performed 101 GC—SC...

... receptor neurons. Responding neurons (87 of 139) could be grouped into five physiological types. Type 1 responded to( R,Z )-6-nonen-2-ol and type 2 to its enantiomer( S,Z )-6-nonen-2-ol, both of which are pheromone components of E. semipurpurella . Type 3 responded to both ( R )-heptan-2-ol and( R,Z )-4...

..., and the findings that led to the appreciation of the vomeronasal organ in mammals as a main chemosensory organ for pheromones mediating reproductive status and inducing sexual behaviour are reported. The anatomical, biochemical and functional properties of the receptor neurones are described. The first...
