adult Drosulfakinin MP1b neuron obsolete descending neuron of the posterior brain DNp62 2024-07-25T12:00:00Z true DNxn089 Obsoleted, as mapped to the Dsk MP1b neuron in Bates et al. (2025) - doi:10.1101/2025.07.31.667571. Type identified at light level and matched across EM datasets by Sturner et al. (2025). Pre- or post-synapse locations are those with the highest total count of these neurons in FlyWire FAFB. Inconsistent neurotransmitter predictions between MANC and FlyWire FAFB. Sturner et al. (2025) note that drivers for DNp61 and DNp62 label the same cell type. Adult descending neuron with its soma in the brain, posterior to the inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). 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 are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024; Sturner et al., 2025). FBbt:20011355 fly_anatomy.ontology DNp61
