Cracking the Olfactory Code


We are part of a multi-investigator project aimed at achieving the first comprehensive characterization of the mammalian olfactory code, ranging from odorant receptors to odor representations and circuitry in the brain to innate odor-driven behavior. We are developing tools to map responses to large numbers of odors across the olfactory bulb and to link these response patterns to identified odorant receptors and their known response specificity. This project is funded by NSF as part of the BRAIN Initiative, and we collaborate with five other PIs: Sri Kosuri (UCLA), Hiro Matsunami (Duke), Lisa Stowers (Scripps Research Institute), Vladimir Itskov (Penn State) and Marcelo Magnasco (Rockefeller).
