We present a simple and unbiased olfactory test in mice. With this protocol olfactory discrimination, preference, avoidance and sensitivity to a novel odor as compared to water can be assessed in single behavioral sessions. This method is indicated for a single experimenter and analysis is based on computer-assisted video processing.

Olfactory sensory neurons express a wide variety of axon-sorting molecules to establish proper neural circuitry. This protocol describes an immunohistochemical staining method to visualize combinatorial expressions of axon-sorting molecules at the axon termini of olfactory sensory neurons.
FAQs
Odor-guided behavior can begin with an innate response, but experience may modify how an organism reacts to the same chemical cue. Physiological state and surrounding context also influence this interaction. Consequently, an odor may produce different behavioral outcomes depending on prior exposure, current biological condition, or the situation in which the cue is encountered.
Physiological state, environmental conditions, and context can all shift olfactory preference. Neural processing also matters because signals from the olfactory bulb reach connected brain regions that integrate sensory information with behavioral decision-making. These influences help explain why responses to a particular odor may vary among individuals or change under different biological circumstances.
Comparing responses under different experience histories can help separate an innate reaction from one shaped by learning. A consistent response across relevant conditions may suggest a stronger innate contribution, whereas changes after exposure indicate that experience affects the outcome. This distinction is useful for studying how sensory cues become associated with feeding, mating, avoidance, or social behavior.
A preference assay measures behavioral responses to selected odors and compares whether an organism favors or avoids them. Researchers can then relate the observed choice or bias to sensory perception, experience, physiological state, and context. The resulting behavioral pattern provides an experimental basis for examining how chemical cues influence biological decisions without relying only on neural measurements.
Altered odor preferences can indicate that genetic factors or neural circuits influence sensory processing and behavior. By examining how responses differ under defined biological conditions, researchers can investigate where odor-guided decisions may be changed. Such results can also help connect receptor-driven sensory signals with broader behavioral outcomes processed through the olfactory bulb and related brain regions.
These measurements support research on feeding, mating, predator avoidance, social communication, and learning. They can also reveal how environmental conditions or disease affect odor-guided behavior. Studying multiple species broadens the biological context, allowing investigators to examine how sensory cues contribute to survival, reproduction, communication, and adaptive decisions across organisms.
