General Information
Term larval antennal lobe broad local neuron ID (Ontology) FBbt:00111700 (Fly Anatomy)
Definition GABAergic intrinsic neuron of the larval antennal lobe that displays broad (panglomerular) arborization (Berck et al., 2016). Its soma is located ventrolaterally to the antennal lobe and it has no axon (Berck et al., 2016). It is synapsed to and by olfactory receptor neurons (ORNs) and olfactory projection neurons (PNs) (Berck et al., 2016). There are five of these cells per hemisphere, which can be divided into two types, trio and duet (Berck et al., 2015). Neurons of the duet type receive more input from ORNs, send more output to projection neurons, and show stronger postsynaptic inhibition than the trio type (Berck et al., 2015). Neurons of the trio type synapse onto each other more often than the duet neurons (Berck et al., 2015).[ FlyBase:FBrf0216269 FlyBase:FBrf0232785 ]
Also Known As "broad LN" ; "broad local neuron" ; "dorsolateral ALN type 1A" (for all, see Synonyms field below)
