Cover picture: Confocal micrograph of the third cardiac chamber showing localization of postsynaptic glutamate IIA receptors (GluRIIA) at cardiac synapses in adult Drosophila melanogaster. Green fluorescent protein (GFP)-immunoreactive (IR) transverse nerves and cardiac terminals are shown in red. GluRII-IR clusters (green) are visible along both main neuronal branches and cardiac terminals. Regions of colocalization are visualized in yellow. Pericardial cells with green fluorescent nuclei are also visible surrounding the chamber. For details, see the article by Dulcis and Levine in this issue (pages 271–280).
