A definition of social buffering and potential pitfalls were summarized in Neuroscience & Biobehavioral Reviews. [PubMed]


Research Interest

To understand animals' mind. Animals of social species communicate not only their physiological status, including their health and reproductive availability, but also their emotions, such as fear, anxiety, or relief. These might be good experimental models for understanding the neural mechanisms of emotion in animals because they involve a specific causative signal, which evokes emotion in these communications. Using rats, I'm currently studying the "alarm pheromone" that is released by stressed rats and augments stress responses in others, and "social buffering" in which the presence of a non-stressed rat suppresses a variety of stress responses in the other rat.

In addition, I recently start to analyze "wild rats" in order to verify our knowledge found in laboratory animals. Wild rats generally avoid even small and harmless novel objects, contrasting laboratory rats that approach and investigate them. I beleive that the difference in avoidance between wild and laboratory rats originates from differences in brain activities related to fear and anxiety neural circuits.

Because their gregariousness and sociality appear to underlie such emotional communication, I believe that we can understand animals' natural lives more accurately when we analyze their emotion and emotional communication.
