Topic: ovipositor extrusion

Multisensory integration plays an important role during decision-making in naturalistic settings. Here, we dissect circuit mechanisms underlying multisensory integration in Drosophila melanogaster, focusing on neurons that directly drive and modulate mated female rejection behavior (ovipositor extrusion or OE) during courtship. DNp13 is a descending neuron that is both necessary and sufficient for OE (Wang et al. Current Biology, 2020); pC2l neurons, which are activated by male courtship song (Deutsch et al. Current Biology, 2019), provide direct presynaptic input to DNp13 (Wang et al. Current
