This database of images depicts the spatial distribution of 2-deoxyglucose uptake evoked in the glomerular layer of the rat olfactory bulb in response to a wide range of defined odorant stimuli, an archive that is being provided as a service to the olfactory research community. Visitors are invited to browse the site using the navigation bar on the left and/or to search the site using a variety of provided search tools. A number of different display tools are provided, allowing the patterns to be viewed from different perspectives. (Some of the more advanced tools require you to download software.) We hope that the time you spend here will be valuable.
