unpaired neuron larval dopaminergic TM1 neuron larval dopaminergic TM1-1 neuron 2013-05-08T02:34:50Z Dopaminergic cells were identified by double labeling with a tyrosine hydroxylase (anti-TH) antibody and a TH-GAL4 driver (FBtp0020119) (Selcho et al., 2009). TM1-1 neuron FBbt:00110328 VFB:FBbt_00110328 fly_anatomy.ontology Subtype of the dopaminergic TM1 neuron that has symmetrical arborizations in the subesophageal and thoracic ganglia. It is an unpaired neuron whose primary process splits into four secondary neurites with two of these running along the midline dorsally and the other two projecting laterally. Secondary neurites innervate the first thoracic segment and the basal subesophageal ganglion.
