Olfactory Study

Olfactory study is the scientific investigation of how organisms detect, process, and respond to odors, providing insight into sensory perception and behavior. Odorant molecules activate receptors in the olfactory system, which converts chemical information into neural signals that the brain interprets and integrates with context, memory, and other sensory cues. In behavioral research, olfactory studies examine how smells influence attraction, avoidance, feeding, social interaction, learning, and environmental responses. These findings help researchers link sensory mechanisms to observable behavior and clarify how organisms use chemical signals to navigate changing surroundings.

We describe here a method for biopsying olfactory mucosa from rat and human nasal cavities. These biopsies can be used for either identifying molecular anomalies in brain diseases or isolating multipotent adult stem cells that can be utilized for cell transplantation in animal models of brain trauma/disease.
