Interpersonal neurobiology (IPNB) or relational neurobiology is an interdisciplinary framework that was developed in the 1990s by Daniel J. Siegel, who sought to bring together scientific disciplines to demonstrate how the mind, brain, and relationships integrate.
Daniel J. Siegel, M.D. is a pioneer in the field called interpersonal neurobiology which seeks the similar patterns that arise from separate approaches to knowledge. This interdisciplinary approach invites all branches of science and other ways of knowing to come together and find the common principles from within their often disparate approaches to understanding human experience. Sciences contributing to this exciting framework include the following:
Interpersonal neurobiology weaves research from these areas into a consilient framework that examines the common findings among independent disciplines. This framework provides the basis of interpersonal neurobiology. The mind is defined and its components necessary for health are illuminated.
Under the umbrella of interpersonal neurobiology, Dr. Siegel’s mindsight approach applies the emerging principles of interpersonal neurobiology to promote compassion, kindness, resilience, and well-being in our personal lives, our relationships, and our communities. At the heart of both interpersonal neurobiology and the mindsight approach is the concept of “integration” which entails the linkage of different aspects of a system—whether they exist within a single person or a collection of individuals. Integration is seen as the essential mechanism of health as it promotes a flexible and adaptive way of being that is filled with vitality and creativity. The ultimate outcome of integration is harmony. The absence of integration leads to chaos and rigidity—a finding that enables us to re-envision our understanding of mental disorders and how we can work together in the fields of mental health, education, and other disciplines, to create a healthier, more integrated world.
Integration is at the heart of interpersonal neurobiology. Defined as the linkage of differentiated components of a system, integration is viewed as the core mechanism in the cultivation of well-being. In an individual’s mind, integration involves the linkage of separate aspects of mental processes to each other, such as thought with feeling, bodily sensation with logic. In a relationship, integration entails each person’s being respected for his or her autonomy and differentiated self while at the same time being linked to others in empathic communication.
For the brain, integration means that separated areas with their unique functions, in the skull and throughout the body, become linked to each other through synaptic connections. These integrated linkages enable more intricate functions to emerge—such as insight, empathy, intuition, and morality. A result of integration is kindness, resilience, and health. Terms for these three forms of integration are a coherent mind, empathic relationships, and an integrated brain.
This highly integrative field is not a division of one particular area of research, but rather is an open and evolving way of knowing that invites all domains of both academic and reflective explorations of reality into a collective conversation about the nature of the mind, the body, the brain, and our relationships with each other and the larger world in which we live. This emerging approach is fundamental to exploring a range of human endeavors, including the fields of mental health, education, parenting, organizational leadership, climate change intervention, religion, and contemplation. Knowing about the way the focus of attention changes the structure and function of the brain throughout the lifespan opens new doors to healing and growth at the individual, family, community, and global levels.
