The cell body fiber projects to and arborizes with the pedunculus where it bifurcates, with one branch turning posteriorly to extensively arborize in the calyx with a few fibers extending into the lateral horn. The other branch projects anteriorly through the pedunculus, turns medially and runs below the medial lobe. The fiber then turns dorsally and bifurcates, forming terminals in the crepine in both hemispheres. There is one of these cells per hemisphere (Aso et al., 2014; Li et al., 2020). It is involved in retrieval of reward and punishment memory (Ichinose et al., 2021). It develops from the larval MBON-a2 (Truman et al., 2023). memory
