fruitless expressing neuron oviposition descending neuron oviDN oviposition descending neuron oviDNb 2020-11-23T08:48:19Z oviDNb fly_anatomy.ontology Oviposition descending neuron with bilateral arborization in the abdominal neuromere, which is relatively anterolateral to that of other oviDN cell types (Wang et al., 2020; Sturner et al., 2025). In the brain, it bifurcates near the midline forming a dorsal projection that arborizes in the superior medial protocerebrum, as well as a ventral descending branch (Wang et al., 2020; Sturner et al., 2025). There is one of these cells per hemisphere (Sturner et al., 2025). It expresses fruitless, but not doublesex (Wang et al., 2020). VFB:FBbt_00049921 oviDNb FBbt:00049921
