Interpersonal Neurobiology (IPNB)
Interpersonal Neurobiology (IPNB) is an integrative psychotherapy developed by Daniel Siegel in 1999. Its core mechanism: integration across neural networks (bilateral, vertical, temporal) through attuned relationship; expanding window of tolerance. This catalogue links it to complex trauma and attachment and relational patterns, typically in individual format, framework.

How Interpersonal Neurobiology works
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
Therapeutic Voice
"Let's put a word on it before we go any further. Not the whole story, just the feeling. What's the closest word you've got?"
View of the Person
A developing brain-mind that achieves health through integration of differentiated neural systems within attuned relationships

Clinical cautions and blind spots
Assessment and precautions
Active psychosis, clients who experience brain-based explanations as reductive or invalidating, situations requiring concrete behavioral intervention
Blind spots
Framework too broad to test empirically; integration language can become vague; not a clinical method itself, and its most common misuse is neuroscience language standing in for relational engagement, since narrating a client's amygdala to them is not the same as being with them and the vocabulary is authoritative enough to make the substitution hard to notice
Philosophical roots
Siegel (interpersonal neurobiology); complexity theory (emergence, integration); Hebb (neurons that fire together); Bowlby (attachment shapes brain); Buddhism (mindfulness integration)
Compared with other approaches
IPNB in 1 Comparative Clinical Vignette
Each vignette presents the same client through multiple theoretical lenses side by side — showing how IPNB formulates presenting problems, sets treatment focus, and sounds in the consulting room compared with other approaches. This comparative pedagogy is unique to Epoché Clinical; no other clinical reference systematically formulates the same case across traditions.

What is the 'window of tolerance'?
Show answer
Zone where one can experience emotions without overwhelm (hyperarousal) or shutdown (hypoarousal).
