Term adult TwoLumps ascending neuron ID (Ontology) FBbt:00049915 (Fly Anatomy)
Definition Adult ascending neuron with its soma in the mesothoracic neuromere, dendritic arborizations in the ipsilateral mesothoracic and prothoracic neuromeres, and axonal projections that ascend to the ipsilateral side of the central brain to the vest, flange, and the lateral accessory lobe (Sen et al., 2019). It is activated downstream of mechanosensory neurons and is involved in backwards locomotion, upstream of the moonwalker descending neurons (Sen et al., 2019). There is one of these cells per hemisphere (Sen et al., 2019).[ FlyBase:FBrf0244359 ]
Also Known As"adult TLA neuron" ; "AN17A026" ; "TLA"
