The Chemical Stimulus and Its Detection

Show Summary Details

Preview

Tetrapods have three chemosensory organs: a gustatory organ, an olfactory organ, and a vomeronasal organ. These chemosensory organs detect sets of chemical stimuli with differing behavioral significance. This chapter discusses the properties of chemical stimuli and identifies which properties are relevant for detection and perception by chemosensory organs. It discusses volatility, solubility, and polarity, and their role in determining which chemosensory organ detects a given stimulus.

Keywords: tetrapods; chemosensory organs; gustatory organ; olfactory organ; vomeronasal organ; chemical stimuli; volatility; solubility; polarity
