| Term |
distal medullary amacrine neuron Dm3 |
ID (Ontology) |
FBbt:00003770 (Fly Anatomy) |
| Definition |
Distal medullary wide-field amacrine neuron whose cell body is located in the cell body rind of the medulla. It projects asymmetrically along layers M2 and M3A forming mixed morphology arborizations (Morante and Desplan, 2008; Fischbach and Dittrich, 1989). The arborization is proximal to that of Dm15 in M2 and distal to Dm4, Dm12 and Dm20 in M3B. Its arbor has a distinct narrow and elongated shape, covering one column wide and 10 columns long. The arbors overlap significantly between cells, aligning with rows of medulla columns, and extending in one of two orthogonal orientations. It is a glutamatergic neuron (Raghu and Borst, 2011). There are two subtypes with different dendrite orientation, synaptic partners and gene expression (Ozel et al., 2021).[ FlyBase:FBrf0049410 FlyBase:FBrf0204652 FlyBase:FBrf0213690 FlyBase:FBrf0228639 FlyBase:FBrf0247762 ] |
| Also Known As |
"Dm3" |
| Comment |
The neurotransmitter was assessed by labelling cells with a vGlut[CNSIII]-GAL4 driver (FBti0129148) (Raghu and Borst, 2011). Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. |
