| Outline of Final Research Achievements |
We recorded neural activity from socially interacting rat in a semi-naturalistic situation and investigated neural correlates with social behaviors. To this end, first, we developed a 3D-video analysis system and a method for identifying rats that emitted vocalizations. Then, based on these new techniques, we analyzed the neural activity in the amygdala. We found that the amygdalar neurons responded differently to the ultrasonic vocalizations emitted by the self and the partner. We also found that the firing rates of the amygdalar neurons changed depending on the spatial relationships between the interacting rats. These results indicate that the amygdala processes not only the actions of the self and the partner but also physical relationships between them, which are important information for executing appropriate social behaviors.
