Neuronal Basis of Innate Olfactory Attraction to Ethanol in Drosophila
Figure 3
The Tdc2-GAL4 activates UAS transgenes in a subset of TbH positive neurons.
The GAL4 expression domain of the Tdc2-GAL4line is visualized by GFP in comparison to TbH expression in the anterior (a) and posterior (b) part of the adult brain. Neurons expressing TbH (G0a) or GFP (G5a) and neurons expressing both (VMI) are highlighted with an arrow (a). In the back of the brain G4a neurons only express TbH, whereas VMII and VMIII neurons express both (b). The expression of Tbh (c to f) and GFP (c′ to f′) is found in the same set of neurons of the G3a/AL2 cluster (c′′), VMI (d′′), VMII (e′′) and VMIII (f′). The analysis of expression patterns is summarized in table g and clusters in which GFP and Tbh co-localize are highlighted in grey. The scale bar represents 25 µm.
