There are four subtypes, collectively having presynaptic terminals in all glomeruli (Wolff et al., 2015). They have inhibitory output onto E-PG neurons in their output glomeruli and receive input from E-PG neurons of other PB regions (Turner-Evans et al., 2020). They are glutamatergic (Turner-Evans et al., 2020) and all develop from neuroblast PBp1 (Kandimalla et al., 2023). intrinsic large-field element of the pb Δ7 Δ7 fly_anatomy.ontology VFB:FBbt_00049807 FBbt:00049807 protocerebral bridge 18 glomeruli neuron PB interneuron Delta7 adult PBp1 lineage neuron adult glutamatergic neuron bilateral
