Olfactory combinatorial coding supports risk–reward decision-making in <i>Caenorhabditis elegans</i>
Olfactory-driven behaviors are essential for animal survival, but mechanisms for decoding olfactory inputs remain poorly understood. We have used whole-network Ca 2+ imaging to study olfactory coding in Caenorhabditis elegans . We show that the odorant 1-octanol is encoded combinatorially in the periphery as both an attractant and a repellent. These inputs are integrated centrally, and their…
