When I explain IFS (Internal Family Systems) Parts Work Therapy to clients, I emphasize that the "parts" in IFS are understood as metaphors for distinct, specialized neural networks in the brain (see links for my other IFS articles at the end of this article).
IFS uses personalized, conversational language that most adults can understand, like "inner child", "protector parts" and "inner critic" as a way to make the these concepts accessible.
Neurobiological research shows that these "parts" are actually clusters of interconnected neurons that fire together during past experiences to form fixed behavioral, emotional and cognitive patterns.
What is the Connection Between IFS Parts Work Therapy and Neural Networks?
Parts Are Encapsulated Neural Networks:
- Implicit Memory Storage: When you experience trauma or chronic stress, your brain encodes the event into implicit memory (i.e., unconscious memory). The neural network formed during that event becomes localized and isolated.
- Fixed Schemas: These isolated neural networks serve as mental maps or schemas. When triggered by a current event, the entire historical network fires simultaneously which causes you to feel, think and react in the same way as when this network was formed. In IFS, this is known as a part "blending" with you.
Neuroplasticity and Memory Reconsolidation
- Unlocking the Network: IFS Parts Work targets these specific neural networks by a process called memory reconsolidation. When you focus on a particular part with curiosity and compassion, you stimulate and open up that specific neural pathway.
- Rewiring Through "Core Self Energy": By introducing "Core Self Energy" (a state of calm, curiosity, clarity and mindfulness associated with your precortex functioning), you can introduce new, positive emotional input into the activated network. According to neuroscientists, including Frank Anderson, MD, this targeted imagination and dual attention physically rewires the neural network, updates the old memory and stores it back in healthy, integrated state (see my article: Healing Unresolved Trauma and Neuroplasticity: The Mind Has a Powerful Innate Ability to Heal Itself).
Regulating Brain Regions
- Calming the Amygdala: IFS "protector parts" (like an inner critic or an anxious part) are driven by an hyperactive amygdala, which is the brain's threat-detection center. "Befriending" these parts tells your amygdala that the danger has passed, which down- regulates the fear response (see my article: Making Friends With Your Inner Critic as a way to understand the "befriending" process in IFS).
- Strengthening the Prefrontal Cortex: The "Core Self" of IFS represents a state of high neurological integration. Practicing IFS strengthens the connection between the prefrontal cortex (executive control) and the limbic system (emotions) allowing you to observe intense emotional reactivity without being completely overwhelmed by it.
Summary of Parallel Concepts
- IFS Concept: A "Part"
- Neurological Equivalent: A localized cluster of neurons forming an implicit memory network
- IFS Concept: A "Blended State"
- Neurological Equivalent: The automatic, involuntary firing of a trauma-encoded neural pathway
- IFS Concept: Core Self Energy (also referred to as "Self')
- Neurological Equivalent: Prefrontal cortex activation, high neurological activation and mindfulness.
- IFS Concept: "Unburdening"
- Neurological Equivalent: Neuroplastic reorganization and memory reconsolidation
Conclusion
IFS Parts Work Therapy uses a personalized language as a way to make the IFS concepts understandable to clients.
In this article I have addressed the neurological equivalents of IFS Parts Work Therapy as a way to show that IFS, which is a gentle evidence-based therapy for trauma, has neurological underpinnings for clients who are interested in the connection between IFS and science.
Get Help in IFS Therapy
If you have been struggling and traditional talk therapy hasn't helped you, you could benefit from working with a licensed mental health professional who is an IFS therapist.
A skilled IFS therapist can help you to work through psychological trauma so you can live a more fulfilling life.
