The main interest of the lab is to understand how activity in neuronal circuits gives rise to stimulus perception and innate behavior in mammals. As an entry point, we are studying the mouse olfactory system. The vertebrate olfactory system is a remarkable molecular recognition device, and is arguably the most genetically tractable of the senses in any species. In addition, odors can elicit specific behavioral responses in mice.
Olfactory stimuli are detected by an array of sensory neurons in the nasal cavity, each of which expresses a single odorant receptor gene. Neurons expressing the same receptor make specific connections to discrete structures (called glomeruli) in the olfactory bulb. In this way, the odorant receptor repertoire (~1000 genes in the mouse) is mapped onto the array of glomeruli in the brain. Our laboratory uses a combination of mouse genetics, in vivo imaging, electrophysiology, optogenetics, and behavior to investigate how genetically-defined populations of sensory neurons contribute to olfactory perception.
