| Term |
lobula columnar neuron LC21 |
ID (Ontology) |
FBbt:00111756 (Fly Anatomy) |
| Definition |
Lobula columnar neuron whose cell body lies on the dorsal posterior surface of the lobula (Wu et al., 2016). It has its main dendritic arbors in lobula layers boundaries 2/3, 3/4, 5A/5B and 5B/6, with most synapses around layers 2/3 (Wu et al., 2016; Tanaka and Clark, 2022). Presynaptic sites are observed in layers 3/4 and along the boundary of 5B (Wu et al., 2016). Its arbors span approximately 30 optic columns, overlapping with other LC21 cells (Wu et al., 2016). It projects to an elongated glomerulus in an intermediate position between the dorsal and ventral groups of optic glomeruli of the PVLP (Wu et al., 2016). There are around 87 cells of this type (Wu et al., 2016).[ FlyBase:FBrf0233032 FlyBase:FBrf0234700 FlyBase:FBrf0253297 ] |
