OA-ASM2

ID: FBbt_00110169

Octopaminergic neuron of the ASM cluster which arborizes extensively in the ipsilateral side of the posterior protocerebrum. The primary neurite bifurcates dorsolaterally to the fan-shaped body. The main ipsilateral process projects laterally and ramifies extensively in the ipsilateral posterior protocerebrum, around the pedunculus of the mushroom body. The other process bifurcates again above the fan-shaped body, with the resulting branches running laterally to the midline. Then they project to the posterior where they turn toward the ipsilateral and contralateral inferior protocerebrum, respectively. The contralateral branch crosses the midline dorsal of the fan-shaped body. Each of the two branches arborizes in the inferior and ventrolateral protocerebrum (Busch et al., 2009).

The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) (Busch et al., 2009).
