General Information
Term lobula tangential neuron LT4 ID (Ontology) FBbt:00003863 (Fly Anatomy)
Definition A lobula tangential neuron that enters the lobula through its proximal side where it arborizes to cover much of layer 5 and 6 with distinctive bleb-type terminals from which short fine terminal branches project. It is a glutamatergic neuron (Raghu and Borst, 2011).[ FlyBase:FBrf0049410 FlyBase:FBrf0213690 ]
Also Known As"lobular tangential neuron LT4" ; "LT4"
CommentThe 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).
