Odor representations are structured by heterogeneous tuning and concentration-dependence of functionally distinct olfactory sensory neuron subpopulations.

Jason De Castro, Shawn D. Burton, Joel Hallkaj, Matt Wachowiak

The paper examines how odorant representations in the olfactory bulb are structured by concentration-dependent tuning of functionally distinct OSN subpopulations across different concentration regimes.

Rapid odorant metabolism organizes identity- and timing-based odor representations by olfactory bulb inputs and outputs

Elvis Acquah, Madison A. Herrboldt, Joel Hallkaj, Mona A. Marie, Zhenxing Wu, Jeanne Chaloyard, Isabelle Andriot, Jean‐Marie Heydel, Kai Zhao, Hiroaki Matsunami, Matt Wachowiak

The paper shows that rapid odorant metabolism in the olfactory mucosa generates secondary odorants that reshape odor representations by introducing timing-based distinctions between inhaled and internally-generated odorants.
