C02 Brain representations of familiarity and discomfort during communication　

We approach animal communication from the perspective of the Free Energy Principle. We hypothesize that the exchange of signals in animal communication is a process in which the model of others in the brain is updated and optimized through active inference. To verify this and clarify its neural basis, we will use avian species as a model animal. We will conduct objective analyses using a virtual reality (VR) communication experimental system for birds, as well as behavioral analysis techniques and brain imaging technologies that can capture neural activity corresponding to signals. Based on this technology, we will establish vocal communication between live individuals and VR individuals using a closed-loop experimental system. We will utilize this setup to measure behavioral responses and brain activity when the response signals of the VR individuals are artificially modified during the communication process. Through these analyses, we aim to scientifically elucidate parts of the model of others that forms in the brain during communication and its updating process.
