General Information
Term adult lateral horn PV4a5 neuron ID (Ontology) FBbt:00049388 (Fly Anatomy)
Definition Adult lateral horn neuron of the PV4a5 group that fasciculates with the PV4 primary neurite tract (Frechter et al., 2019; Dolan et al., 2019; Schlegel et al., 2021). It is a secondary neuron that develops from the BLP4 (LHp1) neuroblast (Schlegel et al., 2021). There are approximately 5-6 of these neurons per hemisphere and they are glutamatergic (Schlegel et al., 2021).[ FlyBase:FBrf0242477 FlyBase:FBrf0242628 FlyBase:FBrf0249560 ]
Also Known As "adult LHPV4a5 neuron" ; "adult posterior ventral tract 4 neuron a5" ; "adult PV4a5 neuron" (for all, see Synonyms field below)
Comment Schlegel et al. (2021) list two as LHON, three as LHLN. Neurotransmitter predicted based on lineage (Schlegel et al., 2021). Cell type found in both hemibrain and FAFB (Schlegel et al., 2021).
