Across the animal kingdom, odors are known as potent stimuli that directly steer behavior. In 2007, Hitoshi Sakano and colleagues used the power of mouse genetics to manipulate the odor map in the olfactory bulb. Elegant behavioral, anatomical, and physiological analyses revealed an apparent dichotomy in how the brain interprets the odor map. Their work paved a way to think of behavioral contingencies as part of early olfactory processing, highlighting innate and learned pathways.
