Interpersonal Neurobiology (IPNB)

“The mind is both embodied and relational.”

Dr. Dan Siegel

Interpersonal Neurobiology weaves together science and human connection. Developed by Dr. Daniel Siegel, IPNB explores how our brains, minds, and relationships are interconnected. It’s fascinating to think that our interactions with others—whether nurturing or stressful—literally shape our brains and affect our bodies. Neuroplasticity, or the brain’s ability to change, is central here.

A simple, effective way to understand how the brain works in IPNB is through Siegel’s hand model of the brain.

  • The wrist represents the spinal cord

  • The palm is the brainstem

  • The thumb folded into the palm represents the limbic system (responsible for emotions and memories)

  • The fingers folded over the thumb symbolize the prefrontal cortex (involved in higher reasoning, impulse control, and decision-making)

When we experience stress or trauma, this prefrontal cortex can become "disconnected" (known as "flipping your lid"), leaving us driven by emotional impulses from the limbic system. Understanding this model helps us visualize and become more aware of when we're dysregulated and in survival mode, so we can practice getting back into alignment.

Integrating Polyvagal theory further enhances this framework, providing insights into our nervous system’s responses. This understanding aids us in transitioning from states of fight-or-flight to a more regulated, ventral vagal state of safety and connection. I utilize Emotional Freedom Technique (EFT) in this journey, calming the nervous system while tapping into our subconscious patterns and beliefs. The unique nature of EFT bridges cognitive, emotional, and somatic experiences, allowing clients to release stored trauma while fostering a sense of safety in their bodies and rewiring neural pathways.

“Where attention goes, neural firing flows, and neural connection grows”

Dr. Dan Siegel

At its heart, IPNB shows how building healthy relationships can promote emotional regulation, resilience, and well-being. Through simple practices like mindfulness, compassion, and fostering positive connections, we can enhance brain integration and emotional balance. This approach aligns perfectly with my passion for helping people not only regulate their nervous systems but also experience deeper growth through meaningful relationships—starting with the one they have with themselves. My clients can reconnect with themselves and others in a truly transformative way.
