Adult Dh31 neuron with its soma in the dorsal brain and an axon projecting to the corpus allatum (Kurogi et al., 2023). These neurons derive from the larval CA-LP neurons (Kurogi et al., 2023). There are three of these cells per hemisphere (Kurogi et al., 2023). In the female, they are involved in reproductive dormancy (Kurogi et al., 2023). Distinct from the three LP neurons (FBbt:00007432) - different hemibrain body IDs given in Kurogi et al. (2023) supplement. Also present in males, but function not investigated by Kurogi et al. (2023).
Adult Dh31 neuron with its soma in the dorsal brain, medial to CA-LP2, and an axon projecting to the corpus allatum (Kurogi et al., 2023). It is derived from the larval CA-LP1 neuron (Kurogi et al., 2023). There is one of these cells per hemisphere (Kurogi et al., 2023).
Adult Dh31 neuron with its soma in the dorsal brain, lateral to CA-LP1, and an axon projecting to the corpus allatum (Kurogi et al., 2023). These neurons derive from the larval CA-LP2 neurons (Kurogi et al., 2023). There are two of these cells per hemisphere (Kurogi et al., 2023).
Adult descending neuron that has a large soma in the brain. Its dendrites are mainly found in the dorsal brain, including in the optic lobe and lateral horn (Liu et al., 2023). It has extensive axonal arborization in the brain, including the optic lobe, mushroom body and subesophageal zone, as well as all neuromeres of the ventral nerve cord (Liu et al., 2023). It responds to noxiously high temperatures via the painless receptor and releases Allatostatin C to alleviate thermal nociception (Liu et al., 2023). There is one of these cells per hemisphere (Liu et al., 2023).
Adult antennal lobe local neuron that releases Myoinhibitory peptide (Sizemore et al., 2023). These neurons all have a patchy morphology and are also GABAergic (Sizemore et al., 2023). There are approximately 9 of these cells per antennal lobe and they collectively innervate all glomeruli (Sizemore et al., 2023).
An interneuron of the mesothoracic ganglion that secretes allatostatin C. There are two pairs of such neurons. They extensively innervate the dorsal region of the prothoracic and mesothoracic ganglia and send an ascending projection that arborizes around the supraesophageal zone and the inferior dorsal brain. They are present in both sexes. In females, they act downstream of the sex peptide abdominal ganglion neurons (SAGs) to inhibit the biosynthesis of juvenile hormone by the corpus allatum via a hormonal route, thereby contributing to the regulation of vitellogenesis (Zhang et al., 2022).
A small DN3 neuron that projects to the posterior side of the brain (Sun et al., 2022). There are 2 or 3 such neurons per hemisphere. They project dendrites to the accessory medulla and receives excitatory input from the DN1 neurons. They send output to the claw neurons (CL) as part of a DN1-APDN3-CL sleep-promoting feedback loop. They express allatostatin C (AstC).
