Trauma's Residency: Is It Housed In The Mind Or The Body?

Updated: Aug 30, 2023

The complex nature of trauma has been studied by researchers, practitioners, and individuals for decades, prompting a profound exploration into its abode within the human psyche and physiology.


As we deepen our comprehension of the intricate interplay

between mind and body, the question looms larger:

where does trauma truly reside?


Does it reside within the neural pathways of the brain, or does it live in the very fibers of our physical being? Anchoring the discussion in evidence-based research from 2020 to 2023, we weave the groundbreaking Polyvagal Theory of Dr. Stephen Porges and the transformative practice of yoga into the narrative, forging a more profound understanding of trauma's complex dwelling.


The Neurological Aspect: Trauma's Mark on the Brain

Advances in neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), have peeled back layers of the brain's response to trauma. Studies over the years have consistently demonstrated the profound influence trauma wields over brain structures and connectivity, notably within the amygdala and hippocampus, pivotal players in emotional processing and memory formation.


A study by Zoladz and Diamond (2021) investigated the neurobiological metamorphosis that post-traumatic stress disorder (PTSD) instigates. It spotlighted the surge of stress hormones like cortisol post-trauma, orchestrating transformations in brain architecture and network dynamics. It's conceivable that these neural adaptations lay the foundation for the vivid, intrusive memories frequently recounted by trauma survivors.


Embodied Aspects: Tracing Trauma's Ripple in the Body

However, the housing of trauma is not solely scripted within the confines of the brain. Contemporary research illuminates a profound connection between trauma and somatic experiences, indicating that trauma might etch its presence in the corporeal self. This perspective acknowledges that trauma transcends emotional realms, weaving its narrative into the very fabric of the body.


Geller et al.'s study (2022) journeyed into this enigmatic intersection of trauma and the body. Employing a fusion of self-report measures and physiological markers, they painted a portrait of the profound rapport between past trauma and the manifestation of chronic muscle tension, gastrointestinal upheavals, and cardiovascular irregularities. This marriage of emotional trauma and somatic sensibility offers an insight into the intricate weave of psychological and physiological elements.


Polyvagal Theory: Bridging the Gap

Dr. Stephen Porges' groundbreaking Polyvagal Theory offers a thread that weaves together the intricate narrative of trauma's connection between brain and body. This theory introduces a revolutionary perspective: the autonomic nervous system houses not two but three branches—sympathetic, parasympathetic, and the social engagement system (ventral vagal). Trauma disrupts this system, relegating individuals to states of fight-or-flight (sympathetic) or immobilization (dorsal vagal), impinging upon their ability to connect with the world.


Porges' work underscores the symbiotic relationship between the body's physiological response and the brain's perception of safety. Trauma's impact transcends individual dimensions; it orchestrates a symphony of neural pathways, hormonal fluctuations, and bodily sensations.


Yoga: An Embodied System to Healing

In this multifaceted discourse, the ancient practice of yoga emerges as a potential healing modality. Recent years have witnessed a surge in studies that highlight yoga's potential in alleviating trauma's imprints. Yoga, by combining physical postures, breathwork, and mindfulness, offers a unique path to heal both brain and body.


A study by Brown-Greene et al. (2023) examined the effects of yoga on trauma survivors. The findings underscored yoga's ability to regulate the autonomic nervous system, improving symptoms associated with trauma. Yoga's emphasis on embodiment, grounding, and cultivating present-moment awareness aligns seamlessly with the principles of Polyvagal Theory.


Conclusion: A Harmonious Convergence

As our understanding of the nature of how to heal trauma evolves, a resounding consensus emerges: the brain and body are not isolated spheres in this narrative. Evidence from research and the wisdom of Polyvagal Theory resonate with the transformative potential of yoga. Trauma's essence is woven into the intricate dance between these dimensions.


In an era where integrative healing is paramount, a holistic approach that respects the interplay of brain, body, and autonomic nervous system emerges as the compass to navigate the extremely complex symptoms of trauma.


As we continue to explore the interconnectedness between neurological, somatic, and mindful dimensions, we usher in a new chapter that underscores the potency of this holistic tapestry.
