I work primarily in serotonergic modulation within the olfactory circuit of Drosophila melanogaster, the fruit fly. Odor that is detected by our olfactory system goes through a lot of information processing. Within the fly's antennal lobe (AL, an equivalent of the mammalian olfactory bulb), odor information is affected by serotonin, 5-HT. It allows the flexibility of processing through targeting different 5-HT receptor subtypes which have excitatory and inhibitory effects. I am working with a defined cluster of neurons in the AL which expresses all five 5-HT receptor in Drosophila and seek to understand the effects behind the receptor diversity in fly's odor guided behavior. These questions are done using light microscopy and behavioral assays.
