The axons of these neurons innervate a small area at the dorsoposterior edge of the lateral horn. There is around one of these per hemisphere, it fasciculates with the medial antennal lobe tract and it is cholinergic (Bates et al., 2020). Its boutons in the mushroom body calyx are widely distributed, mostly within the ventral half (Li et al., 2020). It is the only uniglomerular projection neuron to receive input in DM1 (Li et al., 2020). FlyBrain_NDB:10493 fly_anatomy.ontology mALT (DM1) DM1 lPN FBbt:00067369 iACT (DM1) VFB:FBbt_00067369 DM1_lPN
