Olfactory bulb top view (IMAGE) Cold Spring Harbor Laboratory Caption CSHL Professor Florin Albeanu and his team trained mice to associate a reward with a different sound or odor—but only one of these stimuli at a time. They found that a feedback loop between the brain’s olfactory bulb (seen here) and olfactory cortex helps the animal rapidly switch between the associations.
