| Outline of Final Research Achievements |
In mice, visual and olfactory cues are responsible for fear-contagion. In observer mice, ACC to PAG circuits in the brain is involved in fear-contagion. TRPV1 is also a regulatory molecule in this circuit. The mice weaned earlier showed decreased capacity of emotional contagion, and physical contact from mom increased ACC oxytocin release in pups. If this oxytocin was blocked, their social cognition and affiliation was impaired.
In dog-human dyad, eye-gaze contact increase oxytocin release in both, and if the dog watch the owner, their emotion became similar to that of the owners. When dogs reunite with their owners, they secret tears via oxytocin.
