General Information
Term larval VUM interneuron ID (Ontology) FBbt:00110182 (Fly Anatomy)
Definition Ventral unpaired interneuron that is located ventrally in the embryonic/larval ventral nerve cord midline, ventral to the VUM motorneurons. It is a GABAergic neuron. There are three of these cells per segment.[ FlyBase:FBrf0072659 FlyBase:FBrf0180108 FlyBase:FBrf0195284 ]
Also Known As "iVUM" ; "ventral unpaired median interneuron" ; "Vi"
Comment Neurotransmitter was assessed by the expression of the glutamic acid decarboxylase 1 (Gad1) and the putative GABA vesicular transporter VGAT (FBgn0033911) (Wheeler et al., 2006).
