CRE021 [FBbt_20001090]

Adult brain-intrinsic neuron of the CRE021 group, with its soma in the brain, anterior to the gall (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 superior medial protocerebrum, the ipsilateral crepine, the ipsilateral mushroom body medial lobe, the ipsilateral superior intermediate protocerebrum, the ipsilateral inferior clamp and the ipsilateral epaulette (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral superior medial protocerebrum, the ipsilateral inferior clamp, the ipsilateral crepine, the ipsilateral epaulette, the contralateral inferior clamp, the ipsilateral superior intermediate protocerebrum, the ipsilateral gorget, the contralateral epaulette and the ipsilateral mushroom body medial lobe (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is gaba (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Adult GABAergic Nervous system primary neuron

Adult brain-intrinsic neuron of the CRE021 group, with its soma in the brain, anterior to the gall (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 superior medial protocerebrum, the ipsilateral crepine, the ipsilateral mushroom body medial lobe, the ipsilateral superior intermediate protocerebrum, the ipsilateral inferior clamp and the ipsilateral epaulette (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral superior medial protocerebrum, the ipsilateral inferior clamp, the ipsilateral crepine, the ipsilateral epaulette, the contralateral inferior clamp, the ipsilateral superior intermediate protocerebrum, the ipsilateral gorget, the contralateral epaulette and the ipsilateral mushroom body medial lobe (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is gaba (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Uncharacterized putative cell type based on Hemibrain data (Scheffer et al., 2020) and updated using FlyWire (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024). Soma locations are based on the closest annotated neuropil region. Pre- or post-synapse locations are the fewest regions that collectively contain at least 80 percent of all pre- or post-synapses of these neurons in FlyWire. Neurotransmitter predictions are from Eckstein et al. (2024). Other annotations are based on annotations in FlyWire and are available in the supplemental material of Schlegel et al. (2024).
