OA-VPM

ID: FBbt_00110148

A bilaterally paired octopaminergic neuron of the VM cluster, whose cell body is located slightly lateral to the midline of the subesophageal zone of the adult brain. VPM neurites do not join the median tract and show asymmetric arborization patterns in the brain and gnathal ganglion, except for OA-VPM1. Spiny dendritic processes are present in the posterior slope, with projections in different areas of the brain forming varicose terminals. Five different subtypes can be identified: OA-VPM1-5 (Busch et al., 2009).

Except for the subtype VPM5, all OA-VPM neurons project dorsally and do not join the median tracts of the OA-VUM neurons. The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) and NP7088-GAL4 (FBti0037217) (Busch et al., 2009).
