This image shows Projection Neurons in the DA1 and VA1d glomeruli of the Drosophila antennal lobes in the brain of a male fly that has just emerged from its pupal casing (0 days old). Synaptic puncta were identified throughout the glomeruli (red) through expression of a tagged variant of the presynaptic active zone protein Bruchpilot. The neurites and cell bodies of these neurons were visualized with a membrane-bound GFP tag (green) and the antennal lobe itself was labelled using N-Cadherin (blue).
