Olfactory signalling in vertebrates and insects: differences and commonalities

  title={Olfactory signalling in vertebrates and insects: differences and commonalities},
  author={Ulrich Benjamin Kaupp},
  journal={Nature Reviews Neuroscience},
Vertebrates and insects have evolved complex repertoires of chemosensory receptors to detect and distinguish odours. With a few exceptions, vertebrate chemosensory receptors belong to the family of G protein-coupled receptors that initiate a cascade of cellular signalling events and thereby electrically excite the neuron. Insect receptors, which are structurally and genetically unrelated to vertebrate receptors, are a complex of two distinct molecules that serves both as a receptor for the… CONTINUE READING
