Synapse locations are given where each cell of this type in neuprint has at least 10 connections. Other information from Nern et al. (2025) supplements. Adult central medulla intrinsic neuron of the Cm19 group (Nern et al., 2025). It receives input in the ipsilateral medulla layer M6, medulla serpentine layer and medulla layer M8 (Nern et al., 2025). It sends output to the ipsilateral medulla layer M6, medulla serpentine layer and medulla layer M8 (Nern et al., 2025). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There are approximately 13 of these cells per hemisphere (Nern et al., 2025).
