Stereotyped Odor-Evoked Activity in the Mushroom Body of <i>Drosophila</i> Revealed by Green Fluorescent Protein-Based Ca <sup>2+</sup> Imaging
To study the representation of olfactory information in higher brain centers, we expressed a green fluorescent protein-based Ca 2+ sensor, G-CaMP, in the Drosophila mushroom bod...
