  • The three main neuron types in the lateral horn of the fruit fly Drosophila melanogaster: Inhibitory projection neurons (green) respond to attractive odors; higher-order neurons of the lateral horn (orange) respond to repulsive odors; excitatory projection neurons (magenta) are likely to convey the identity of an odor. The first two neuron types were examined in the study. (Antonia Strutz/MPI Chem. Ecol.)
