2. What is the vibrational theory of odor receptors?

  • Lock and key theory - whether an odorant molecule smells the same or different to another is based on whether it has a complementary shape to the receptor binding site of the OSN
  • Whether a odorant smells the same or different to another is based on its IR vibrational spectrum
  • Molecules might have to be the right shape to ‘dock’ with receptor sites but then bond energies determine the final activation level

3. True or false, the thalamus shows reliable activity even to odors below threshold?

  • True
  • False

  • 100 ppb
  • 100 ppm
