At its core, interpersonal neurobiology (IPNB) holds that we are ultimately who we are because of our relationships. IPNB combines many scientific disciplines to study connections within a person’s brain, as well as between the brains of different individuals that emerge in their relationships with one another. Given IPNB looks at how our mind, our brain, and our relationships interact to shape who we are, you can think of IPNB as the “triangle of well-being.”

The concept of “integration” is important in understanding IPNB. Integration refers to a person’s use of all parts of the brain system (more specifically, the entire interconnected brain and body neural system), rather than subsets such as the fight-flight-freeze subset. According to IPNB, human beings seek continuous self-organisation toward greater levels of integration between the brain, mind, and relationships. With increased integration between the brain, mind, and relationships with one another, an individual can experience improved health, growth, and restoration.
