General Information

Term

lobula columnar neuron LC24

ID (Ontology)

FBbt:00111759 (Fly Anatomy)

Definition

Lobula columnar neuron whose cell body lies in the ventral area of the lateral cell body rind (Wu et al., 2016). It has its main dendritic arbors in lobula layers 5 and 6, with synapses concentrated in layer 5B (Wu et al., 2016; Tanaka and Clark, 2022). Sparse presynaptic sites are observed throughout the lobula arbors (Wu et al., 2016). Its arbors span approximately 35 optic columns, overlapping slightly with other LC24 cells (Wu et al., 2016). It projects to a small and dorsal optic glomerulus of the PVLP, posterior to LC6 and LC16 glomeruli (Wu et al., 2016). There are around 38 cells of this type (Wu et al., 2016).[ FlyBase:FBrf0233032 FlyBase:FBrf0234700 FlyBase:FBrf0253297 ]

Also Known As

Comment

Pre- versus postsynaptic innervation assessed with a presynaptic marker (synaptotagmin-HA driver) (Wu et al., 2016).
