Cm4 [FBbt_20011382]

Adult central medulla intrinsic neuron of the Cm4 group (Nern et al., 2025). It receives input in the ipsilateral medulla layer M6 (Nern et al., 2025). It sends output to the ipsilateral medulla (Nern et al., 2025). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024; Nern et al., 2025). There are approximately 110 of these cells per hemisphere (Nern et al., 2025).
