Yet, it is unclear how neuronal variability originates, to what extent and at what timescales it exists, and what functional consequences it might carry. Using genetic labeling and electron microscopy connectomics, a team led by Dr. Ya-Hui Chou at Institute of Cellular and Organismic Biology, Academia Sinica, shows that an identified inhibitory olfactory local interneuron, TC-LN, exhibits extraordinary variability in its glomerular innervation patterns. TC-LN\u2019s innervation of the VL2a glomerulus is sexually dimorphic, is influenced by female\u2019s courtship experience, and correlates with food intake in mated females. Mating also affects output connectivity of TC-LN to specific local interneurons. The findings propose that mating-associated variability of TC-LNs regulates how food odor is interpreted by an inhibitory network to modulate feeding.
