General Information
Term adult spirit subesophageal neuron ID (Ontology) FBbt:20003899 (Fly Anatomy)
Definition Adult neuron with its soma in the lateral subesophageal zone (Sterne et al., 2021). It has pre- and post-synapses ipsilaterally in the gnathal ganglia as well as a branch receiving input from the ipsilateral inferior posterior slope (Dorkenwald et al., 2024; Schlegel et al., 2024). It crosses the midline and has inputs and outputs in the contralateral inferior posterior slope (Dorkenwald et al., 2024; Schlegel et al., 2024). It is predicted to be a cholinergic primary neuron (Dorkenwald et al., 2024; Schlegel et al., 2024; Eckstein et al., 2024). There are 2 of these cells per organism (Dorkenwald et al., 2024; Schlegel et al., 2024).[ FlyBase:FBrf0251280 FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "adult CB0045 neuron" ; "CB0045"
Comment FlyWire CB0045 mapped to Sterne et al. (2021) spirit neuron by Shiu et al. (2024) - FBrf0260565. This was identified at light level but not well described/analyzed due to lack of MCFO. Most of this cell description is based on FlyWire data and the supplemental material of Schlegel et al. (2024).
