Its ipsilateral processes are largely dendritic and its contralateral processes are largely axonal (Kind et al., 2021). It receives input from R7 photoreceptors of the dorsal rim area in layer M6 (Kind et al., 2021). It passes through the central brain without forming synapses there (Kind et al., 2021). There are two of these cells per hemisphere, one innervating the ipsilateral anterior medulla and contralateral posterior medulla and one innervating the ipsilateral posterior medulla and the contralateral anterior medulla (Kind et al., 2021).
