[3H]2-deoxyglucose autoradiography has revealed foci in the antennal lobe of Drosophila melanogaster that are active during olfactory stimulation. Labelling in the receptor axons and the lobe interneurons can be observed. Each class of odors stimulates activity in a specific subset of antennal glomeruli. This defines the activity domain, which is recognizably distinct, although overlapping, for different classes of volatile chemicals. Unilateral stimulation with attractants predominantly results in excitation of the ipsilateral glomeruli. Collaterals of the receptor neurons to the contralateral lobe stimulate no visible postsynaptic activity. On the other hand, unilateral stimulation with repellent odors, such as benzaldehyde, results in an equally strong activity in both antennal lobes.
[3H]2-脱氧葡萄糖放射自显影术揭示了黑腹果蝇触角叶中在嗅觉刺激期间活跃的区域。可以观察到受体轴突和叶间神经元中的标记。每一类气味都会刺激触角小球特定子集中的活性。这定义了活性域，对于不同类别的挥发性化学物质，其虽然有重叠但明显不同。用引诱剂进行单侧刺激主要导致同侧小球兴奋。受体神经元到对侧叶的侧支不刺激可见的突触后活性。另一方面，用驱避性气味（如苯甲醛）进行单侧刺激会导致两个触角叶中出现同样强烈的活性。
