| Term | descending neuron of the gnathal ganglion DNg30 | ID (Ontology) | FBbt:00047622 (Fly Anatomy) |
| Definition | Adult serotonergic descending neuron belonging to the DNg group, having a large cell body in the cell body rind of the lateral gnathal ganglion (Namiki et al., 2018; Scheunemann et al., 2018). One branch projects dorsally to arborize and form presynapses in the ipsilateral anterior and posterior ventrolateral protocerebrum, superior clamp and superior lateral protocerebrum (Scheunemann et al., 2018). Another branch crosses the midline just ventral to the esophageal foramen and arborizes in the contralateral gnathal ganglion and saddle, where it also forms presynapses (Scheunemann et al., 2018). It descends on the contralateral side of the cervical connective, then fasciculates with the dorsal lateral tract of the ventral cervical fascicle and innervates the intermediate and lower tectulum, and the abdominal neuromere (Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018; Scheunemann et al., 2018). Its superior clamp arbor outputs to MB-MP1 in the mushroom body pedunculus and it is involved in the initial period of long-term memory consolidation (Scheunemann et al., 2018). It also expresses the sex peptide receptor and myoinhibitory peptide (Mip/AstB) (Scheunemann et al., 2019).[ FlyBase:FBrf0238754 FlyBase:FBrf0239335 FlyBase:FBrf0244287 ] | ||
| Also Known As | "adult gnathal ganglion serotonergic projection neuron" ; "adult Mip inferior contralateral interneuron (ICLI)" ; "DNg30" (for all, see Synonyms field below) | ||
| Comment | Namiki et al. (2018), identify this as being morphologically similar to the inferior contralateral interneuron, described by Jiang et al. (2013) (FBrf0222685). | ||
