It follows the longitudinal ventromedial fascicle, then has dense branches, restricted to the gall and part of the anterior lateral accessory lobe surrounding the gall, containing mainly postsynaptic sites (Omoto et al., 2018; Hulse et al., 2021). It also has mixed terminals in the outer posterior domain of the ellipsoid body (Omoto et al., 2018; Hulse et al., 2021). There is one of these cells per hemisphere and it develops from neuroblast BAmv1 (Kandimalla et al., 2023).
