My laboratory investigates one of the first steps in olfactory perception: the conversion of an odorous stimulus into a nerve signal. Olfactory receptor neurons located in the nose detect odorants and generate the electrical response, which is then conveyed to the brain for further processing. The focus of our research is to understand 1) how olfactory receptor neurons code odor signals of different odorants, 2) the cellular mechanisms that lead to the generation and termination of those responses and, 3) how the characteristics of odorant responses of olfactory receptor neurons drive behaviors. We use electrophysiological and cell imaging techniques, immunohistochemistry and behavioral approaches to address these questions.
