Its main process is in the DRA region, but it also has long processes extending ventrally into non-DRA columns (Kind et al., 2021). It receives input from R7 photoreceptors of the DRA, mainly in layers M6/M7 (Kind et al., 2021). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There are approximately 20 of these cells on each side (Nern et al., 2025).
