receives synaptic input in region sends synaptic output to region lobula tangential neuron lobula tangential neuron LT4 FBbt:00003863 LT4 LT4 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). 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). lobular tangential neuron LT4 fly_anatomy.ontology FlyBrain_NDB:10025 VFB:FBbt_00003863 lobula layer 5 lobula layer 6 adult glutamatergic neuron
