[3H]2-deoxyglucose mapping of odor-induced neuronal activity in the antennal lobes of Drosophila melanogaster.
Olfactory stimulation results in an enhanced uptake of [3H]2-deoxyglucose in specific glomeruli in the antennal lobes of Drosophila melanogaster. Unilateral stimulation induces activity in receptor axons and lobe interneurons on the ipsilateral side. Collaterals from the receptor axons to the contralateral lobe are also active but stimulate either weak or no postsynaptic activity. This difference in signal transfer properties could be relevant to odor detection by flies.
