“We cannot live only for ourselves.

A thousand fibers connect us

with our fellow humans.”

—Herman Melville

The Theory Behind Interpersonal Neurobiology

Interpersonal neurobiology (IPNB) explores the nature of mind, brain, body and the relationship between them throughout life. IPNB confirms the findings of attachment theory and shows, supported by current neuroscientific research, how early attachment experiences form the basis of the wiring of our neural pathways and nervous system and how that wiring influences the way we think, feel, and behave throughout life.

Attachment theorists long recognized the formative and long-lasting influence of early childhood experiences on our self-concept and the nature of future relationships. Our early bonding experiences, mostly in the preverbal stage of our lives, provide the basis for our sense of self, the world and relationships. Our brains encode these experiences as implicit memories throughout the body as sensations, emotions, thoughts, impulses and even images. Often, outside of conscious awareness, these implicit models greatly determine the quality of our present-time lives.

As babies, the only way that we were developmentally able to communicate was through gestures and sound, through our senses. FELT-SENSE of who we are, is processed by the right-hemisphere of our brain and is a to a great part a sensory experience.

Bringing the body to therapy therefore opens us to a well of information that lies beyond cognitive reach but close to the core of our being:

“There is a voice that doesn’t use words. Listen…” (Rumi)

Given the centrality of relational experience in shaping our inner and outer world, interpersonal neurobiology puts the relationship at the heart of therapy. While it was once thought that our early experiences determine who we are, interpersonal neurobiology holds that our brains constantly reshape and reorganize themselves through new experiences and positive relationships throughout our entire lifespan.

“Our brains are genetically hard-wired for attachment and connection.”
