1. When does the OSN fire?

  • When the olfactory epithelium detects molecules
  • When about 8 of its binding sites are filled
  • When it reaches threshold for molecules
  • Only during its preferred cycle time

2. What is the core concept of shape theory?

  • Receptor specificity is based on molecular structure. Oderants must have the right shape to activate the receptor, there is a certain receptor for each molecule
  • Molecules with the same IR vibrational spectrum should smell similar, same shape diff vibrations smell different. Bond energies determine activation level
  • A two-stage theory. Molecules must be the right shape to bond to receptor sites but bond energies determine final activation level.

3. In Wedekind (1995)...?

  • Females not on pill preferred males with similar HLAs. On the pill they also prefered those with similar
  • Females not on pill preferred males with similar HLAs. On the pill they prefered those with different
  • Females not on pill preferred males with different HLAs. On the pill they prefered those with similar
  • Females not on pill preferred males with different HLAs. On the pill they also prefered those with different

4. Where do OSN axons project to?

  • Glomeruli in the olfactory bulb
  • Glomeruli in the olfactory epithelium
  • Glomeruli in the olfactory cleft
  • Glomeruli in the somatosensory cortex

5. Each OSN...?

  • Are resistant to damage due to highly internalised structure
  • Has broad non-specific connections
  • Expresses just one type of receptor
  • Receive input from glomeruli
