Neural Synchronization

How do two brains communicate with one another?

Social interactions between two individuals can be highly intricate, and the brain's activity during these exchanges can be even more complex. fNIRS neural synchronization (also known as hyperscanning) allows researchers to simultaneously monitor the brain activity of two or more individuals, providing unprecedented insights into the neural dynamics of interpersonal interactions.
