#31: Join host Aaron Fournier and functional-medicine detective Dr. Paul Harris for a clear, practical breakdown of the limbic system trauma loop — what it is, how it starts (even in utero), why it produces brain fog, chronic stress and inflammation, and what you can do to reset the system. In this episode we cover:• What the limbic system does and its key parts (thalamus, hypothalamus, amygdala, hippocampus, prefrontal cortex)• How chronic stress, infections (including long-COVID), heavy metals, mold/mycotoxins, EMF exposure and disrupted sleep can trigger or perpetuate a trauma loop• Common signs: persistent brain fog, sleep disruption, exaggerated emotional responses, chronic fatigue, food sensitivities, autoimmune patterns• Assessment options: clinical screening, neuroimaging, limbic trauma questionnaire, targeted toxin/mycotoxin testing (e.g., mercury tri-test, TOTAL TOX)• Actionable interventions: DNRS neuroretraining, somatic trauma work, EMDR, vagal-nerve exercises (cold exposure, gargling, humming), targeted detox and supportive frequency compositions from Soaak• Real outcomes and hope: restoring parasympathetic function, calming immune overreaction, improved cognition and quality of life Reach Dr. Harris: Call (918)551-6600, and ask for Debbie or Stephanie 00:00 Introduction 02:06 What is the limbic trauma loop 04:11 Amygdala vs prefrontal cortex 06:17 Early origins and fetal stress 08:23 What the limbic system does 10:28 Core brain structures overview 12:34 Threat processing and first response 14:40 Hypervigilance and overreactions 16:46 Cell defense mode and inflammation 18:52 Thalamus and hypothalamus roles 20:57 Viral triggers and mitochondria 23:03 Amygdala and autonomic balance 25:09 Hippocampus, memory, and stress 27:13 Frontal cortex and personality 29:19 Signs you’re stuck in a loop 31:25 Assessments and questionnaire 33:30 Triggers: toxins, mold, EMFs 35:36 Treatments: DNRS, vagus work, Soaak frequencies Follow Soaak & The Science of Sound Podcast: Website – Soaak Technologies App – Soaak Frequency Therapy Instagram – @thesoaakpodcast Sponsors:Visit soaak.com/app and enter code Soaakpod for your first month free!
