Synchrony is a research area that focuses on the coordination of activities, behaviors, or physiological responses among individuals or systems. It explores how synchronization can occur in various contexts, such as in social interactions, communication, brain connectivity, and collective behavior in groups. Synchrony can be studied using techniques such as measuring simultaneous brain activity, analyzing patterns of movement coordination, or observing patterns of synchronization in social networks. This research area is important for understanding how individuals connect and interact with each other, and how synchronization processes impact various aspects of human behavior and functioning.
