General Information
Term Y neuron Y1 ID (Ontology) FBbt:00003912 (Fly Anatomy)
Definition Wide-field Y neuron with a wide, unstratified arborization field in all layers of the lobula plate, a wide, thin, terminal arborization domain in lobula layer 5 and a small terminal arborization domain in medulla layer M8 (Morante and Desplan, 2008; Fischbach and Dittrich, 1989). It is a glutamatergic neuron (Raghu and Borst, 2011).[ FlyBase:FBrf0049410 FlyBase:FBrf0204652 FlyBase:FBrf0213690 ]
Also Known As "Y1" ; "Y13"
Comment 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) as assessed by FlyBrain Neuron DB.
