Cilia of olfactory sensory neurons contain proteins of the signal transduction cascade, but a detailed spatial analysis of their distribution is difficult in cryosections. We describe here an optimized approach for whole mount labeling and en face visualization of ciliary proteins.

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.
FAQs
Signals reaching the secondary olfactory cortex are not interpreted in isolation. Inputs from primary olfactory regions, including the piriform cortex, are integrated with limbic and multimodal association networks. This convergence allows neural activity to reflect both odor identity and surrounding context, helping connect a sensory signal with learned meaning, reward, or emotion.
Learning and reward can change how odor-related activity is interpreted. The same chemical cue may acquire different significance depending on prior experience, situational context, or its association with a positive outcome. Examining these influences helps explain why odor perception is not limited to identifying molecules, but can also guide preferences and behavior.
Emotionally significant smells provide a way to examine communication between olfactory processing and limbic networks. Activity in the secondary olfactory cortex can be considered alongside odor identity, context, and learned associations to investigate why particular smells evoke emotional responses. This makes the region relevant to biological studies of perception, memory, and behavior.
A biological investigation can ask how neural activity changes with odor identity, context, learning, or reward. These comparisons help separate the sensory features of an odor from the meaning assigned to it. The resulting evidence can clarify how recognition develops into conscious perception, preference formation, or an odor-guided behavioral response.
Food and chemical preferences can be examined as outcomes of integrated odor processing rather than odor identification alone. When odor information is combined with memory, emotion, context, and reward, researchers can investigate why some cues acquire attractive or aversive significance. This perspective connects olfactory biology with choices and behaviors involving environmental chemicals and food.
Studying these higher-order olfactory networks can help determine which aspects of smell are affected when olfaction is impaired. Researchers can consider whether difficulties involve odor recognition, the emotional or contextual meaning of smells, or links between odor signals and behavior. Such distinctions provide a framework for interpreting smell-related dysfunction within broader neural processing.
