ExR3
ID: FBbt_00047035
Adult serotonergic extrinsic ring neuron that follows the longitudinal superior medial fascicle and innervates the superior medial and intermediate protocerebrum, the crepine, the lateral accessory lobe and a dorsal layer of the fan-shaped body, with mixed terminals (Omoto et al., 2018; Hulse et al., 2021). It has mainly presynaptic terminals in both (bilateral) bulbs and the inner central 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 DM6 (Kandimalla et al., 2023).
Previously assigned to DM3 in Omoto et al. (2018), but same authors assign to DM6 in Kandimalla et al. (2023).
