My research explores the dynamics of olfactory bulb (OB) circuitry, and the roles of oscillatory synchronization in olfactory processing. To this end, I record activity from OB slices with multielectrode arrays in combination with optogenetic and pharmacological approaches. Specifically, using slices from OMP-ChR2 transgenic mice (which express channelrhodopsin-2 in the axon terminals of olfactory sensory neurons), I design and present “artificial odors” to the OB slice by projecting spatiotemporal patterns of light to study olfactory coding.
