General Information
Term adult Drosulfakinin MP1 neuron ID (Ontology) FBbt:00051431 (Fly Anatomy)
Definition Adult neuron that secretes Drosulfakinin and is found in a cluster of two cells close to the midline in the posterior medial protocerebrum (Nichols and Lim, 1996; Namiki et al., 2018; Wu et al., 2019; Bates et al., 2025). It also expresses fruitless and plays a role in mating behavior in both males and females, but it is not sexually dimorphic (Wu et al., 2019). There are two subtypes, both of which are descending neurons that arborize bilaterally in the lateral protocerebrum and subesophageal zone, but differ in whether they innervate the optic lobe (Wu et al., 2019; Bates et al., 2025).[ FlyBase:FBrf0085661 FlyBase:FBrf0219451 FlyBase:FBrf0239335 FlyBase:FBrf0243806 ]
