From the posterior ramifications a single branch emerges and bifurcates in the area dorsolateral to the esophagus foramen. One process projects to the ipsilateral inner medulla and lobula. The other process crosses the midline dorsal to the fan-shaped body and innervates the contralateral inner medulla and lobula (Busch et al., 2009). OA-ASM1 The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) (Busch et al., 2009).
