General Information
Term descending neuron of the outside anterior cluster DNd02 ID (Ontology) FBbt:00047591 (Fly Anatomy)
Definition Descending neuron belonging to the DNd group, having a cell body just lateral to the antennal lobe, on the anterior surface of the brain (Namiki et al., 2018). It belongs to the ventrolateral protocerebrum (VL) cluster of octopaminergic neurons (Busch et al., 2009). In the brain, it has neurites in the anterior and posterior ventrolateral protocerebrum, wedge, vest and gnathal ganglion, spanning both hemispheres (Busch et al., 2009; Namiki et al., 2018). It descends on the ipsilateral side of the cervical connective, then fasciculates with the dorsal lateral tract of the ventral cervical fascicle (Namiki et al., 2018). It innervates the intermediate and lower tectulum, abdominal neuromere, T1, T2 and T3 leg neuropils, wing sensory neuropil, and T1, T2 and T3 medial ventral and ventral association centers, mainly ipsilaterally (Namiki et al., 2018). There is one of these cells per hemisphere (Busch et al., 2009; Namiki et al., 2018). It is glutamatergic and tyraminergic (Cheong et al., 2024), as well as octopaminergic (Busch et al., 2009).[ FlyBase:FBrf0207458 FlyBase:FBrf0239335 ]
