General Information
Term adult lateral horn PV4k1 neuron ID (Ontology) FBbt:00049918 (Fly Anatomy)
Definition Adult lateral horn output neuron of the PV4k1 group that fasciculates with the PV4 primary neurite tract (Schlegel et al., 2021). Most of its input and output terminals remain within the lateral horn. It is a secondary neuron that is part of the LHp1 (BLP4) lineage (Schlegel et al., 2021). There are 2-3 of these cells per hemisphere and they are glutamatergic (Schlegel et al., 2021).[ FlyBase:FBrf0249560 ]
Also Known As "adult posterior ventral tract 4 neuron k1" ; "adult PV4k1 neuron" ; "LHPV4k1"
Comment Cell type found in both hemibrain and FAFB (Schlegel et al., 2021). Neurotransmitter predicted based on lineage (Schlegel et al., 2021). One PV4a5 cell in FAFB was retyped to PV4k1 - https://orcid.org/0000-0002-1373-1705.
