Trauma Neuroscience

Trauma neuroscience occupies a pivotal and contested position within the depth-psychology corpus, serving simultaneously as empirical substrate and theoretical horizon for somatic, dissociation-based, and relational approaches to traumatic suffering. Van der Kolk’s The Body Keeps the Score anchors the field’s most comprehensive synthesis, documenting how trauma inscribes itself neurologically—altering brain architecture, disrupting hemispheric integration, and reorganizing the body’s physiological responses in ways that resist purely verbal or cognitive remediation. Ogden and the sensorimotor tradition draw directly on neurobiological research to argue that trauma treatment must engage subcortical and somatic pathways unavailable to top-down, language-mediated interventions. Lanius and colleagues supply the functional neuroimaging evidence undergirding claims about right-hemisphere dominance during traumatic recall, HPA axis sensitization, and the long-lasting neurobehavioral sequelae of childhood adversity. Running beneath these convergent threads is a productive tension: whether neuroscientific findings should discipline clinical technique or whether, as Levine’s somatic phenomenology suggests, embodied intuition must hold its own against the abstractions of brain science. The Polyvagal Theory (Porges) and interpersonal neurobiology (Siegel) extend the framework toward autonomic regulation and relational development, binding individual neurobiology to dyadic and social contexts. Across voices, trauma neuroscience functions less as a settled paradigm than as a generative pressure, compelling clinicians to reckon with the body’s mnemonic sovereignty.

extreme, repetitive or abnormal patterns of stress such as abuse and related adverse experiences during critical or circumscribed periods of childhood brain development can impair, perhaps permanently, the activity of major neuroregulatory systems, with profound and lasting neurobehavioral consequences

Lanius and colleagues present the foundational neuroscientific claim that early-life trauma permanently impairs neuroregulatory systems, grounding subsequent clinical and developmental arguments in empirical brain research.

neuroimaging studies in PTSD also offer evidence of differences in lateralization secondary to trauma, with increased brain activity during recall of traumatic memories in the right hemisphere and decreased brain activity in the left hemisphere

Ogden, drawing on Lanius’s neuroimaging research, identifies lateralization asymmetry as a neuroscientific signature of traumatic memory recall, distinguishing it from ordinary autobiographical remembering.

what may appear to be a horizontal disconnection between lower and upper brain structures in PTSD as well as evidence supporting relative right dominance during traumatic memory recall… the brain appears to have another alternate connection between the hemispheres, sometimes referred to as the ‘subcortical bridge’

Ogden maps the neurobiological architecture of PTSD onto a horizontal cortical-subcortical disconnection, proposing that the subcortical bridge offers a therapeutic pathway bypassing language-dependent cortical circuits.

overwhelming experiences affect the development of brain, mind, and body awareness, all of which are closely intertwined. The resulting derailments have a profound impact on the capacity for love and work

Lanius’s endorsement of van der Kolk’s work encapsulates the field’s central thesis: that traumatic experience neurologically reorganizes brain, mind, and body in ways that comprehensively damage human functioning.

Trauma is not primarily remembered as a story, but is stored in mind and brain as images, sounds, smells, physical sensations, and enactments. Our research showed that talking about traumatic events does not necessarily allow mind and brain to integrate the dissociated images and sensations

Van der Kolk’s research, cited in Courtois, delivers a key neuroscientific finding: traumatic memory is encoded in sensorimotor and imagistic form rather than narrative, challenging the sufficiency of verbal therapeutic approaches.

Ruth Lanius’s confidence in this work and in its relevance for even the most traumatized individual, and her contributions to this book, including her clarity about the possible implications of current neuroscience research for trauma treatment

Ogden credits Lanius’s neuroscience research as a direct intellectual resource for the clinical application of sensorimotor therapy, marking an explicit bridge between laboratory findings and treatment design.

structural dissociation of the personality is a theoretical construct that conceptualizes traumatic dissociation along the lines of action systems theory as an adaptive, neurobiologically organized response to trauma

Ogden frames structural dissociation as a neurobiologically organized adaptive response, integrating trauma neuroscience with action systems theory to account for the compartmentalization of personality following trauma.

early maternal separation is associated with heightened stress sensitivity, as evidenced by enhanced release of ACTH and cerebrospinal norepinephrine in response to acute stress, in addition to decreased inhibitory GABAergic tone

Animal model data cited by Lanius demonstrate that early social deprivation produces measurable neuroendocrine alterations—HPA sensitization, norepinephrine elevation—providing biological substrate for developmental trauma theory.

Levine’s work is characterized as moving fluidly between evolutionary neuroscience, Polyvagal theory, and somatic practice, positioning trauma neuroscience as the scientific backbone of embodied therapeutic intervention.

brain activity depends on both chemical and electrical signals. The subsequent dominance of pharmacology almost obliterated interest in the electrophysiology of the brain for several decades

Van der Kolk historicizes trauma neuroscience by tracing how pharmacological dominance suppressed electrophysiological brain research, framing neurofeedback’s resurgence as a recovery of neglected scientific terrain.
