part of innervates adult brain adult lateral horn primary neurite tract adult posterior ventral primary neurite tract 5 2020-04-29T12:00:00Z PDL19 Primary neurite tract of the posterior ventral (PV) adult brain in the fifth clockwise position (from posterior perspective), from ventrolateral to dorsal to ventromedial, of PV tracts that enter the lateral horn (Frechter et al., 2019). It contains the primary neurites of neurons of the dorsal hemilineages of neuroblasts DL1 and DL2 (Schlegel et al., 2021). Lateral horn neurons that enter the neuropil via this tract are predominantly output neurons (Frechter et al., 2019). fly_anatomy.ontology FBbt:00049292 PDL23 adult PV5 primary neurite tract PDL22 VFB:FBbt_00049292 PDL05
