Dr. Hansma's Scientific Research: Neurons Self-Fire in Brain Organoids Causing Chronic Pain

Below is a link to a mind‑expanding YouTube talk featuring Dr. Paul Hansma, Professor of Physics at UC Santa Barbara and head of the Hansma Research Lab. In this remarkable presentation, Dr. Hansma reveals cutting‑edge discoveries in brain science that could completely transform how we understand chronic symptoms.

I’ve summarised the key takeaways below — but truly, imo it’s worth watching the full video. It blew my mind. His team has identified the actual physical mechanism that drives pain and many chronic symptoms — and crucially, they’ve shown why recovery looks different for everyone. Each brain’s “alarm wiring” is unique, which explains why different calming or reprocessing methods work for different people.

Strikingly, Dr. Hansma’s findings align with the principles behind Pain Reprocessing Therapy (PRT) and Dr. John Sarno’s pioneering mind‑body approach— including Sarno’s idea of talking to the brain and practising self‑soothing to calm inner tension and the advice to get on with normal life as best one can, despite the pain or other symptoms. Dr. Hansma’s lab provides the scientific confirmation for what Sarno and others intuited: the brain’s alarm circuits can be overprotective, but they’re also trainable.

-------------------------------------------------------------------------------------------------------------------

What Dr Hansma and his team's research shows...

• Chronic pain isn’t psychological — it’s neurological. It stems from maladaptive neural firing patterns, not from tissue damage or imagination.
  
  
• The brain acts like a gatekeeper, filtering sensations and deciding which ones to notice. For example, your foot presses on the ground all day, yet your brain filters it out because it doesn’t view that sensation as dangerous.
  
  
• Dr Hansma and his team found that when a negative emotion (fear, anger, anxiety) becomes linked with a normal body sensation, the brain suddenly becomes interested. It tags that signal as meaningful, checks it repeatedly, and can start amplifying it into pain.
  
  
• Their research with human brain organoids (tiny clusters of neurons) shows neurons can self‑activate in loops even with no input — meaning that chronic pain can keep running long after an injury has healed.
  
  
• Over time, the pattern locks in: sensation → fear or tension → more sensation → more fear.
  
  
• All sensations we experience — from pain to fatigue — are created by neural activity. Which sensations reach awareness depends on the brain’s sense of safety.
  
  
• For acute injury, the system works perfectly; for chronic issues, it keeps misfiring even when tissues are fine.
  
  
• The “source” of chronic pain isn’t the body part, but the firing pattern in the brain’s sensory map of that area.
  
  
• Dr Hansma shared a striking personal example: he once had severe shoulder pain that was accompanied by visible inflammation. When he successfully retrained his brain’s danger response, the pain faded — and the inflammation subsided too. It demonstrated that calming the neural alarm can physically quiet the body’s inflammatory process.
  
  
• Recovery comes from teaching the brain that it’s safe again.

• Dr. Hansma notes that the longer you've had chronic symptoms, the easier—and often quicker—recovery becomes, because extended duration provides clear evidence that the issue isn't life-threatening (your body hasn't fallen apart despite years of pain). This realization dissolves fear, making it simpler for the brain to release its overprotective firing patterns once you apply safety-focused techniques.

-------------------------------------------------------------------------------------------------------------------

This fits with Alan Gordon’s PRT and Dr Sarno’s message of treating symptoms with understanding instead of panic. Education, reassurance, and emotional soothing work not because pain is “all in your head,” but because they change the firing of the overactive circuits themselves.

• Understanding that pain comes from protective brain patterns helps dissolve fear.
  
  
• Calming techniques — slow breathing, visualisation, gentle self‑talk — shift the body from threat to rest‑and‑digest, changing neural activity in real time.
  
  
• Self‑soothing, which Sarno wrote about, is one of the fastest ways to calm these circuits. Gentle reassurance, kindness toward yourself, and emotional softening tell the brain, “I’m safe now.”
  
  
• These mechanisms show up across conditions such as CFS/ME, fibromyalgia, long Covid, POTS, IBS, migraines, and more.
  
  
• Even when scans show apparent damage (old injuries, arthritis), pain intensity still depends largely on brain amplification — and that part is changeable.
  
  
• The Hansma Lab now measures comfort, calm, and safety instead of pain, because what we focus on, we reinforce.

The above suggests a “how to recover” roadmap along the lines of the following:

1. Reframe what your symptoms mean

“This is real, but it’s my brain being overprotective — not damage.”
When symptoms rise, pause and remind yourself: “It’s just a misfire. My body is safe.”

2. Shift focus from pain to safety

Instead of “How bad is this?”, ask “How safe or supported do I feel?”
Even a 5 % increase in ease tells the brain, “See? We can relax.”

3. Practise calm on purpose

Try a few safety tools and repeat often:

• Slow breathing (in 4, out 6–8)
  
  
• Visualising a peaceful or enjoyable place
  
  
• Softening muscles around the symptom
  
  
• Looking around and naming what feels okay right now
  
  
• Returning to a self‑soothing cue — a phrase, image, or object that brings calm

4. Talk to your brain directly (Sarno style)

“Thank you, brain — I know you’re protecting me, but we’re safe now.”

Pair this with a gentle tone or gesture to help the body believe it.
(On a personal note, I’ve found that telling my brain it’s being 'ridiculous' has sometimes stopped a symptom in its tracks!)

5. Re‑engage with life in tiny steps

Bring back small, meaningful activities and interests that you like and enjoy doing and experiencing, using your safety tools, effectively saying to and showing the brain: “I can move — and it’s safe.”

6. Track calm, not pain

Rate your sense of safety or comfort 0–10. Each small moment of calm gets you closer to recovery.

7. Practise frequently, not perfectly

This is training for your neural calm. Every repetition of reassurance and self‑soothing rewires the circuitry.

-------------------------------------------------------------------------------------------------------------------

Ultimately, Dr Hansma’s research gives hard science to what Dr Sarno and modern mind‑body work have shown all along:

Chronic pain is a reversible 'habit' of the nervous system.

When you understand it, speak kindly to it (and occasionally point out its mistakes!), and self‑soothe rather than fear it, your brain learns what it most needs to know — that you are, and always have been, safe.

 

Wow! That is so much great information here! Thank you for sharing. I bookmarked this post!
