octopaminergic AL2b neuron [FBbt_00110145]

Octopaminergic neuron of the AL2 cluster which innervates both the ipsilateral and contralateral optic lobes. Secondary processes originating in the esophagus foramen bilaterally innervate both lobulae. Additional processes branch off this neurite to innervate the posteriolateral, posterioinferior lateral and ventrolateral protocerebra, forming varicose terminals. There is one subtype of OA-AL2b neurons: AL2b1 (Busch et al., 2009). One other subtype, AL2b2 was described, although its identity as octopaminergic neuron was not confirmed. 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).
