Real time odor representations

The relative importance of spatial and temporal patterning of odor-evoked activity in the olfactory bulb is controversial. Recently, voltage-sensitive dye imaging has been used to demonstrate that odor-evoked glomerular patterns evolve over time in an odor-specific manner. The results suggest that odor information is contained in a combination of spatial and temporal response components. Fast voltage-sensitive dye imaging of neural dynamics in the olfactory bulb suggests that odor representations are structured in the spatial and temporal domains
