Innervation of the lateral accessory lobes is postsynaptic, whilst that of the fan-shaped body, in layer 2, is presynaptic (Young and Armstrong, 2010; Hulse et al., 2021). The cell bodies of neurons in this class are found in the anterior brain, dorsal to the antennal lobes (Young and Armstrong, 2010).
