New SE Research Reflection: Interoception and Dissociation

A new systematic review in Neuroscience & Biobehavioral Reviews examines the relationship between interoception and dissociation. Across thousands of screened articles, only a small number met inclusion criteria, but the majority of those studies found significant differences in interoceptive processing in individuals experiencing dissociation.
From a Somatic Experiencing® (SE) perspective, this is a meaningful convergence.
SE has long understood dissociation not as absence, but as a protective reorganization of the nervous system, where access to bodily signals, orientation, and present-moment experience becomes disrupted.
This review gives empirical support to something many clinicians observe:
When interoceptive signals are dysregulated, unclear, or overwhelming, the capacity to feel “here, in this body” can fragment.
Connections to SE Theory
This research aligns closely with core SE principles: Interoception as foundation of presence. The felt sense is not optional—it is central to self-experience.
Dissociation as protection, not pathology
1) A system may reduce access to internal signals to prevent overwhelm.
2) Gradual restoration of capacity
3) Tracking sensation, titration, pendulation, and orienting all support safe re-engagement with the body.
4) Regulation before intensity
Without sufficient autonomic stability, increasing interoceptive awareness can amplify dysregulation rather than resolve it.
🔹 Important Research Takeaways
The evidence base is still small and heterogeneous
Interoception is multi-dimensional (accuracy, awareness, sensibility), and not consistently measured
More research is needed to clarify causality and mechanisms
🔹 Why This Matters
This paper strengthens an emerging bridge:
👉 Dissociation can be understood, in part, as a disruption in how the brain and body integrate internal signals
👉 Effective trauma treatment must work with the body’s signaling systems, not just cognition
👉 Restoring interoceptive capacity is not just awareness—it is restoring the conditions for presence
SE has been working clinically with these processes for decades. This review helps bring that work into clearer dialogue with contemporary neuroscience.
