Area of Science:

  • Olfactory neuroscience
  • Chemosensation
  • Molecular biology

Background:

  • Mammalian olfactory system distinguishes volatile molecules with subtle structural differences.
  • Synthetic chemistry provides diverse odorants, including sandalwood compounds used in fragrances.
  • Understanding olfactory receptor activation by specific odorant classes is crucial.

Purpose of the Study:

  • To investigate the activation profile of endogenous olfactory receptors by sandalwood odorants.
  • To identify olfactory receptor neurons specifically responsive to sandalwood compounds.
  • To determine if olfactory receptors can discriminate between sandalwood odorants with minor structural variations.

Main Methods:

  • Exposure of dissociated rat olfactory receptor neurons to sandalwood oil and synthetic sandalwood molecules.
