Subject of research
1.	ace-to-face communication is "changing another person's mental state by sharing information, ideas, or attitudes." Using two functional MRIs to examine neural activity during communication, synchronization of neural activity was observed,indicating mental sharing. This is a shared state of mind. To investigate what happens to this shared state of mind in a group, my research theme is to connect MRIs via the Internet to examine the neural activity of communication at the group level.

Research summary
Exploring Mechanisms of Well-Being Enhancement through Communication Prior to my research on the neural basis of communication, I had studied the dramatic neuroplasticity that occurs when visual or auditory input is lost. At that time, I learned that the loss of sensory input significantly impacts communication development, and I was eager to learn more about the developmental process of social skills, so I continued my research. We chose this topic to clarify how the limitation of direct human-human contact, such as the recent coronary disaster, affects human social skills. Direct face-to-face communication is essential for human well-being, but its neural basis is poorly understood. To establish a method to enhance well-being through communication, we aim to first clarify the neural basis of well-being, identify the factors that enhance well-being, analyze how face-to-face communication relates to these factors, and finally explain the mechanisms at the group level. Ultimately, we aim to clarify the mechanism at the group level. As a roadmap for our research, we will first establish a system that simultaneously performs functional MRI and EEG measurements and an experimental system that connects multiple MRIs via the Internet. Happiness has two aspects, comfort and satisfaction. After clarifying the neural basis of these two aspects, we intend to explain how communication promotes these two aspects at the level of neural activity. Through this research, we believe we can contribute to the physiological significance of behavioral measurement indices in collaboration with the project on quantifying communication quality through multimodal measurement at Ritsumeikan University.

Message
1.	Since the project aims to enhance well-being through communication, we think it would be good to expand the project into joint research on sports, an essential well-being facilitator.
