OA-AL2

ID: FBbt_00110139

Octopaminergic neuron whose cell body is located in a cluster in the ventromedial border of the antennal lobe. One neurite runs along the esophagus foramen to the posterior slope where it branches, forming spiny dendritic arborizations. It has axonal projections that innervate the optic lobe. There are seven cells in this cluster that belong to two main subtypes, OA-AL2i and AL2b (Busch et al., 2009).

The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) and NP7088-GAL4 (FBti0037217). Post- versus pre-synaptic innervation was determined using the postsynaptic marker Rdl-HA or the presynaptic marker Synaptotagmin-HA (Busch et al., 2009).
