It has a domain of spiny fibers in the ipsilateral lateral accessory lobe (ventral body) and presynaptic terminals in a ventral layer of the fan-shaped body (Hanesch et al., 1989). median fan-shaped neuron Fm2 FBbt:00007510 Fm2 neuron Fm2 adult ventral fan-shaped body adult ventral fan-shaped body tangential neuron
