sends synaptic output to region inner medulla lobula octopaminergic AL2i neuron octopaminergic AL2i2 neuron 2012-10-08T04:42:58Z VFB:FBbt_00110142 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). Octopaminergic neuron of the AL2 cluster which innervates the ipsilateral inner medulla and lobula. Secondary processes branch off the neurite that projects from the posterior slope to the optic lobe and innervate the ipsilateral posteriolateral and ventromedial protocerebra, forming varicose terminals (Busch et al., 2009). OA-AL2i2 ipsilateral octopaminergic neuron of the antennal lobe OA-AL2i2 FBbt:00110142 fly_anatomy.ontology
