General Information

Term

larval ascending moonwalker-like backward neuron

ID (Ontology)

FBbt:00052653 (Fly Anatomy)

Definition

Larval neuron with its soma in the subesophageal zone (SEZ), dendritic arborization from the SEZ to the mesothoracic neuromere, and ascending axonal projections to the brain (Omamiuda-Ishikawa et al., 2020). There is one of these cells per hemisphere and it is cholinergic (Omamiuda-Ishikawa et al., 2020). It is activated by blue light, downstream of class IV dendritic arborizing neurons (Omamiuda-Ishikawa et al., 2020). It outputs onto and can activate the mooncrawler descending neurons to stimulate backwards locomotion (Omamiuda-Ishikawa et al., 2020).[ FlyBase:FBrf0247105 ]

Also Known As

"larval AMB neuron"

Comment

Does not fit FBbt definition of ascending as soma is in SEZ and not VNC.
