IN21A004 [FBbt_20010621]

Adult intrinsic neuron of the IN21A004 group with ipsilateral arbors in a single VNC neuromere (Takemura et al., 2024; Marin et al., 2024). It is a primary neuron of the 21A hemilineage (Takemura et al., 2024; Marin et al., 2024). It receives input in the leg neuropil and sends output to the leg neuropil (Takemura et al., 2024; Marin et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 6 of these cells per organism and their somas are found in the mesothoracic neuromere, metathoracic neuromere and prothoracic neuromere (Takemura et al., 2024; Marin et al., 2024).
