These neurons receive input mainly in ventral layers of a fan-shaped body column and have predominantly presynaptic terminals in the rubus and the surrounding crepine (Hulse et al., 2021). They follow a nine-column organization in the fan-shaped body (Hulse et al., 2021). FR Stated to innervate round body (ROB) in a couple of places in Hulse et al. (2021), but this is probably a mistake.
