Bringing research from the lab to the home, from a controlled environment to real life, can be a way to understand human interaction. As technology evolves, its potential grows, driving both scientific exploration and real-world applications. In this sense, the authors of a new study have taken a step forward to understanding what happens at the brain level when two people come into contact and interact with each other, such as during a conversation, when giving each other a gift, or in other situations of cooperation.
