General Information
Term adult bilateral inferior posterior slope neuron ID (Ontology) FBbt:20004075 (Fly Anatomy)
Definition Adult interneuron with its soma posterior-ventral to the gnathal ganglia (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral inferior posterior slope, where it is targeted by ipsilateral horizontal system neurons and contralateral H2 neurons (Schlegel et al., 2024; Dorkenwald et al., 2024; Erginkaya et al., 2025). It has presynapses in the contralateral inferior posterior slope, where it outputs to HSN and HSE cells (Schlegel et al., 2024; Dorkenwald et al., 2024; Erginkaya et al., 2025). It is GABAergic (Eckstein et al., 2024; Erginkaya et al., 2025). There are 2 of these cells per organism (Erginkaya et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262578 ]
Also Known As "adult bilateral IPS neuron" ; "adult CB0268 neuron" ; "bIPS" (for all, see Synonyms field below)
Comment Cell type from FlyWire (Schlegel et al., 2024; Dorkenwald et al., 2024), renamed and identified in hemibrain and at light level by Erginkaya et al. (2025). Soma location based on the closest annotated neuropil region. Mapped to FlyWire CB0268 based on body IDs and Codex annotations (2025-05-06).
