In mice, the ability to detect pheromones is principally mediated by the vomeronasal organ (VNO). Here, an acute tissue slice preparation of VNO for performing calcium imaging is described. This physiological approach allows observations of subpopulations and/or individual neurons in a living tissue and is convenient for receptor-ligand identification.

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction. Types of Communication A common form of communication is visual. Visual communication can be...

FAQs
The main olfactory system and vomeronasal organ provide two neural routes through which pheromone-related cues can be detected. Their inclusion in research helps investigators examine how chemical information enters sensory processing and connects with downstream neural circuits. Comparing these routes clarifies how detection relates to distinct behavioral or physiological responses within the same species.
After detection, neural circuits do more than register the chemical cue: they translate it into coordinated behavioral or physiological responses. Depending on the signal and biological context, those responses may include attraction, territorial behavior, aggression, or reproductive changes. Studying this translation connects sensory neuroscience with brain activity and hormone regulation, rather than treating behavior as an isolated output.
The effects of a pheromone cue are shaped by interactions among genes, the environment, and neural circuitry. This means the same general communication system can be studied as an integrated biological process rather than as a fixed stimulus-response pathway. Research that considers these influences can explain variation in social behavior and in the physiological consequences associated with chemical signaling.
Studies of pheromone communication can follow the link from molecular detection to brain activity, hormone regulation, and social behavior. This framework supports questions about how sensory cues influence behavior and physiology, and how those effects are organized in the nervous system. It also gives researchers a way to connect molecular-level events with observable outcomes in animal models.
In studies of mating systems, pheromone communication provides a chemical-signaling perspective on how members of a species influence one another. Researchers can examine how attraction or reproductive changes fit within broader social interactions, while also considering neural circuits and hormones. This makes the topic useful for linking reproductive behavior with sensory processing and physiological regulation.
Within neuroscience, the topic is relevant because it connects sensory detection with social processing in the brain. Animal models allow investigators to study how olfactory pathways, neural circuits, and hormone-related mechanisms contribute to behaviors such as aggression, territorial responses, or attraction. This perspective helps organize social behavior as an interaction among molecular cues, neural activity, and physiology.
