sends synaptic output throughout fan-shaped body layer 2 adult lateral horn output neuron adult lateral horn-fan-shaped body layer 2 neuron 2020-05-01T12:00:00Z adult posterior ventral tract 5 neuron k1 FB2H LHPV5k1 FB2I adult PV5k1 neuron fly_anatomy.ontology Adult lateral horn output neuron that has wide-field (tangential) presynaptic arborization in fan-shaped body layer 2 (Dolan et al., 2019; Hulse et al., 2021). There are four of these neurons per hemisphere and they are glutamatergic (Dolan et al., 2019) and they develop from the CP2 neuroblast (Kandimalla et al., 2023). Hulse et al. (2021) say LHPV5k1 likely corresponds to FB2H_a, FB2H_b and/or FB2I_b, as does Schlegel et al. (2021) supplement. Schlegel et al. (2021) map this type to a different tract than other PV5 neurons, so PV5k1 name is misleading and this neuron is not part of the DL2 dorsal or DL1 dorsal hemilineage. All FB2I and FB2H mapped to CP2 lineage in Kandimalla et al. (2023). Dolan et al. (2019) say this is glutamatergic (based on immunohistochemistry), but Schlegel et al. (2021) predict cholinergic based on lineage. adult lateral horn PV5k1 neuron VFB:FBbt_00049419 FBbt:00049419 adult LHPV5k1 neuron adult fan-shaped body layer 2 neuron of CP2 lineage adult glutamatergic neuron
