IN21A021 [FBbt_20010638]

Adult intrinsic neuron of the IN21A021 group with bilateral arbors in multiple VNC neuromeres (Takemura et al., 2024; Marin et al., 2024). It is a secondary neuron of the 21A hemilineage (Takemura et al., 2024; Marin et al., 2024). It receives input in the T3 leg neuropil and abdominal neuromere and sends output to the T3 leg neuropil (Takemura et al., 2024; Marin et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 2 of these cells per organism and their somas are found in the metathoracic neuromere (Takemura et al., 2024; Marin et al., 2024).
