Several experiments suggest that the binding of carbon dioxide to its specific receptor, Gr21a, in a particular subset of ORNs is sufficient to mediate avoidance behavior in flies, much like activation of the AWB neurons in C. elegans. Briefly describe a novel experiment to confirm that activation of Gr21a-expressing neurons is sufficient for odorant avoidance in flies.
