How they work
IPNB
Core mechanism: Integration across neural networks (bilateral, vertical, temporal) through attuned relationship; expanding window of tolerance
Ontology: Impaired neural integration from relational/developmental experience; integration = mental health
Mentalization-Based Tx (MBT)
Core mechanism: Improved mentalizing capacity (understanding mental states in self and others) reduces affective dysregulation and interpersonal chaos
Ontology: Failure of mentalization under attachment stress; inability to represent mental states leads to impulsive action

What each assumes — and misses
IPNB
Philosophical roots: Siegel (interpersonal neurobiology); complexity theory (emergence, integration); Hebb (neurons that fire together); Bowlby (attachment shapes brain); Buddhism (mindfulness integration)
Blind spots: Framework too broad to test empirically; integration language can become vague; not a clinical method itself
Therapeutic voice: When you can name the feeling, you can tame the feeling. Let's try: what would you call this state?
Mentalization-Based Tx (MBT)
Philosophical roots: Bion (containment, alpha function); Winnicott (holding); Jessica Benjamin (mutual recognition); Theory of Mind research; Hegel (recognition as constitutive)
Blind spots: Slow skill-building may frustrate clients seeking symptom relief; less structured intervention for acute crises
Therapeutic voice: What do you imagine was going on in her mind when she said that?
Choosing between them
IPNB (Integrative) and Mentalization-Based Tx (MBT) (Psychoanalytic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
