General Information
Term descending neuron of the posterior brain DNp04 ID (Ontology) FBbt:00047637 (Fly Anatomy)
Definition Descending neuron belonging to the DNp group, having a cell body on the posterior surface of the brain (Namiki et al., 2018). This neuron does not cross the midline and descends on the ipsilateral side of the cervical connective (Namiki et al., 2018). It has neurites in the anterior ventrolateral protocerebrum, posterior ventrolateral protocerebrum, gnathal ganglion and lower tectulum (Namiki et al., 2018). It fasciculates with the ventral medial tract of the ventral cervical fascicle in the ventral nerve cord (Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018). It is cholinergic (Cheong et al., 2024). It receives a large amount of its input from LC4 visual projection neurons (Dombrovski et al., 2023).[ FlyBase:FBrf0239335 FlyBase:FBrf0255530 ]
Also Known As"DNlt004" ; "DNp04"
CommentNamiki et al. (2018), identify this as being morphologically similar to the ipsilateral small descending neuron, described by Milde and Strausfeld (1990) (FBrf0239829).
