General Information
Term adult Drosulfakinin MP1b neuron ID (Ontology) FBbt:00051434 (Fly Anatomy)
Definition Adult Drosulfakinin MP1 neuron that does not project to the optic lobe (Wu et al., 2019). In the brain, it has postsynapses in the ipsilateral superior lateral and intermediate protocerebrum and superior clamp, and presynapses in the gnathal ganglion, the ipsilateral and contralateral anterior ventrolateral protocerebrum, the ipsilateral superior lateral protocerebrum and the contralateral flange (Schlegel et al., 2024; Dorkenwald et al., 2024). Within the VNC, it fasciculates with the median tract of dorsal cervical fasciculus I and sends output to multiple regions (Takemura et al., 2024; Marin et al., 2024). There is one of these cells per hemisphere (Wu et al., 2019; Schlegel et al., 2024; Dorkenwald et al., 2024; Sturner et al., 2024).[ FlyBase:FBrf0243806 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "descending neuron of the posterior brain DNp62" ; "DNxn089" ; "DSKMP1B"
Comment Pre- or post-synapse locations are those with the highest total count of these (DNp62) neurons in FlyWire FAFB. Sturner et al. (2024) note that drivers for DNp61 and DNp62 label the same cell type.
