The Evolution of the Somatic Storage Metaphor
For over a decade, the field of trauma therapy has been dominated by the concepts popularized by psychiatrist Bessel van der Kolk in his 2014 bestseller, The Body Keeps the Score. Van der Kolk’s work suggested that traumatic experiences alter the nervous system so fundamentally that the trauma becomes physically lodged in the body’s tissues, muscles, and fascia. This model was a revolutionary departure from traditional "talk therapy," emphasizing that because the body "remembers" the threat, recovery must involve physical release.
While the "body storage" model provided a lifeline for millions of patients who felt traditional psychiatry ignored their physical symptoms, it has faced increasing scrutiny from the scientific community. Critics argue that the idea of memories being "stored" in muscle tissue lacks a clear biological mechanism. The new paper by Kotler, Mannino, and colleagues seeks to bridge this gap, offering a more precise neurobiological explanation for why trauma feels physical without resorting to what they deem a "scientifically problematic" metaphor.
The Predictive Coding Model: A Shift in Perspective
The core of the authors’ argument rests on "predictive coding," a theory of brain function championed by Karl Friston. In this model, the brain is not a passive receiver of sensory information; rather, it is a proactive "prediction engine." It constantly generates internal models of the world to anticipate what will happen next, using sensory data from the body and the environment only to update or correct these predictions.
In a healthy individual, these predictions are flexible and update rapidly when new information suggests a situation is safe. However, in the wake of significant trauma, this predictive system can become rigid. The brain begins to assign an overwhelming "weight" to the possibility of threat. Consequently, the nervous system enters a state of hypervigilance where it no longer accurately assesses safety.
Michael Mannino, the chief science officer of the Flow Research Collective and a distinguished research fellow at Florida Atlantic University, explains that this rigidity is the true hallmark of trauma. "It is more likely a problem in how the brain predicts threat, safety, agency, and action," Mannino stated. Under this view, when a trauma survivor experiences a racing heart or muscle tension, it is not a "release" of a stored memory, but rather the brain’s predictive machinery misinterpreting internal bodily signals as evidence of an imminent, recurring threat.
Metastability and the "Stuck" Brain
A critical concept introduced in the paper is "metastability"—the brain’s ability to fluidly transition between different functional networks and mental states. High metastability allows for cognitive flexibility, enabling a person to shift from a state of high focus to relaxation or from fear to curiosity as the environment changes.
The authors posit that trauma reduces the brain’s metastability. The nervous system becomes trapped in "narrow, inflexible states of fear," or what scientists call "rigid attractor dynamics." In this state, the brain’s repertoire of possible responses shrinks. The individual becomes "stuck" in a threat-detection loop, unable to access the neural states required for play, creativity, or social connection. By reframing trauma as a loss of metastability, the researchers move the target of treatment from "excavating" old memories to "restoring" neural fluidity.
The Role of Flow States in Recovery
One of the most innovative aspects of the paper is the link between trauma recovery and "flow states." Flow is a state of optimal experience characterized by complete absorption in a task, a distorted sense of time, and a reduction in self-referential thought. During flow, the brain’s "task-positive" networks are highly active, while the "default mode network" (associated with rumination and self-criticism) and the amygdala (the brain’s threat center) tend to quiet down.
The authors argue that flow training may be an effective intervention for trauma because it directly targets the predictive system. Flow requires the brain to process information rapidly and adapt to challenges in real-time, which necessitates a high degree of metastability.
"If trauma involves rigid threat prediction, then flow may help by creating conditions where the nervous system learns, experientially, that challenge can be navigated safely and effectively," Mannino noted. The research points to action sports athletes and individuals in high-stakes environments who, despite facing repeated danger, often exhibit high levels of resilience. This suggests that the experience of danger itself does not cause trauma; rather, it is the inability to navigate that danger with agency and flexibility that leads to the "stuck" predictive patterns of PTSD.
Cultural Implications and the "Trauma Identity"
Beyond the biological mechanics, the authors address the sociological impact of the "body keeps the score" narrative. They express concern that the metaphor of "hidden trauma deposits" may unintentionally encourage an external locus of control and a "victim-centric" identity.
If a person believes their trauma is a physical object buried in their fascia that can only be removed by a specialist, they may feel less empowered to engage in their own recovery. Mannino argues that the "storage" metaphor can lead to a chronic reactivation of painful memories, as individuals are encouraged to constantly scan their bodies for "stored" pain.
By contrast, the prediction-based model emphasizes that the brain is predicting the present and future based on the past. This shifts the focus toward training the brain to make better, more flexible predictions in the "here and now." This approach aligns with modern resilience data, such as that provided by Columbia University researcher George Bonanno, which suggests that humans are naturally more resilient than the "permanent damage" model of trauma implies.
Reinterpreting Body-Based Therapies
The authors are careful to state that their theory does not invalidate the effectiveness of somatic therapies, massage, or breathwork. Instead, they offer a different explanation for why these treatments work.
In the traditional model, a massage therapist "releases" a trauma from a muscle. In the predictive coding model, the physical sensation of the massage creates a "prediction error." When the therapist applies pressure to a tight area, the brain receives a strong sensory signal. It searches for a reason for this tension and may pull up a traumatic memory as an explanatory model. The therapeutic benefit comes not from the "release" of a stored memory, but from the brain’s ability to process that sensation in a safe, controlled environment, thereby updating its predictive model of the body.
"The goal should not be to banish bodywork from trauma recovery," Mannino said. "The goal should be to get the mechanism right so we can improve the interventions." Understanding that the body is a "messenger" rather than an "archive" allows clinicians to refine techniques to maximize "interoceptive precision"—the ability to accurately read and interpret the body’s internal signals.
Future Research and Performance Neuroscience
The publication of this paper marks the beginning of a broader effort to formalize the field of "Performance Neuroscience." Kotler and Mannino are scheduled to release a textbook on the subject in July, which will explore the biological mechanisms behind stress regulation, flow, and peak human achievement.
The researchers have outlined several directions for future empirical testing to validate their theoretical claims:
- Neuroimaging Studies: Using fMRI and EEG to measure metastability and neural complexity in trauma populations before and after flow-based interventions.
- Comparative Trials: Directly comparing the outcomes of somatic-based therapies versus flow-based interventions (such as adventure therapy or skill-acquisition tasks).
- Cross-Disciplinary Analysis: Investigating whether "rigid prediction" is a common factor in other conditions, such as depression, addiction, and neurodegenerative diseases like Parkinson’s.
The ultimate goal is to move the mental health field toward a "performance-based" approach. Rather than merely aiming for the absence of symptoms, this new paradigm seeks to restore a person’s full capacity for agency, adaptability, and high-functioning states.
Conclusion: A New Roadmap for Healing
The assertion that "the body does not keep the score" is not a dismissal of the physical suffering of trauma survivors, but a call for a more precise scientific understanding of that suffering. By moving the focus from "storage" to "prediction," Kotler, Mannino, Fox, and Friston offer a roadmap for recovery that is grounded in the brain’s inherent plasticity.
This shift suggests that while the past may have shaped the brain’s current "software," that software is constantly being updated. Through interventions that promote mental flexibility—whether through flow states, cognitive reframing, or refined somatic practices—individuals can retrain their nervous systems to move beyond the rigid predictions of the past and reclaim a sense of safety and agency in the present. As the field of performance neuroscience matures, it promises to provide more actionable, empowering tools for those looking to not just survive trauma, but to thrive beyond it.
