vagus nerve nucleus tractus solitarius brainstem

The Nucleus Tractus Solitarius: The Brainstem Inbox Where Your Whole Body Checks In

Taste, blood pressure, oxygen levels, gut stretch, immune signals — nearly every sensory report the vagus carries lands in one small brainstem structure. Understand that single overloaded inbox and you understand why one sensitized hub can throw symptoms across your entire body at once.

vagus nerve fawn response trauma

The Fawn Response: Trauma's Most Missed Autonomic State

Fight and flight are obvious. Freeze is recognized. The fourth survival response — fawn — is the one almost no one sees, because it looks like kindness. Polyvagally, it is a hybrid defense state wearing the clothing of safety.

vagus nerve panic attacks anxiety

Panic Attacks Through a Polyvagal Lens: Why Your Body Sounds the Alarm Without a Threat

Acid Reflux Is a Vagus Nerve Story: GERD Through the Autonomic Lens

Heart Palpitations and the Vagus Nerve: When the Beat Is Loud but Not Dangerous

vagus nerve hypersensitivity hyperacusis

Sensory Hypersensitivity and Hyperacusis: When the Nervous System Has the Volume Cranked Up

Hyperacusis and broader sensory hypersensitivity are not "personality traits." They are signatures of central sensitization in a nervous system that has lost its parasympathetic dampening — and the vagus nerve is one of the few accessible levers.

vagus nerve dizziness pppd

Chronic Dizziness Without a Diagnosis: PPPD and the Vestibulo-Autonomic Link

When the workup is "normal" but the dizziness persists, the answer is often PPPD — a chronic functional vestibular disorder driven by a brain stuck in postural threat detection, with autonomic and vagal dysregulation as the engine.
