Vagus Nerve & the Mind-Body Connection

March 25, 2010

The vagus nerve is a cranial nerve, a honking big nerve that runs from your skull, down your chest and into your abdomen. The punch-in-the-gut feeling of a jolt of adrenalin/the start of an anxiety attack is carried on the vagus nerve.

The usual paradigm for emotions is they start in the brain. Most of the body’s hormones have a dual purpose as a neurotransmitter. The vagus nerve helps coordinate the physical feeling with the emotional feeling – they are one and the same. The mind-body connection.

Most of the body’s serotonin is in the gut. A squirt of serotonin doesn’t just happen in the brain, it happens in the whole body. Ditto adrenaline. The vagus nerve conducts information in both directions. I don’t think it’s entirely accurate to blame anxiety on a brain malfunction.

An interesting treatment for anxiety is “Vagus Nerve Stimulation.” In VNS, a device is implanted that applies current to the vagus nerve is to overwhelm it. It’s kind of like a TENS unit for pain. VNS is a last resort for intractible anxiety.

One implication of this is that if you can control the physical aspects of anxiety – relax your muscles, slow down your breathing & heart rate – then the emotional component will follow. Once the emotions are managed you can work out whatever brought on the anxiety.
Candace Pert, Ph.D. discovered opium (endorphin) receptors in the brain. She wrote an enlightening book Molecules Of Emotion: The Science Behind Mind-Body Medicine.

Also check out Timothy Leary. One of his more interesting ideas is that we have receptor sites for chemicals that haven’t been invented yet. Alexander Shulgin was a chemist who formulated a lot of them, but I don’t recommend you try it. 🙂

The Neurology of Trauma

March 7, 2009

A few weeks ago there was a vehicle in front of me at the coffeeshop window with a phone number and link to The Evolutionary Brain. I called the number and got the guy in the truck, we waved at each other, and he gave me a DVD of the above video, Dr. Robert Scaer on Brain State Technologies and Trauma.

I had a theory about this 18 years ago when I worked for an EEG company and was getting into brainwave synchronization. Doesn’t it seem obvious that if you can “read” brainwaves, then you can also write them? It would be tricky. We’re not looking for ECT, which is more like an electromagnetic pulse (EMP) that wipes the whole thing clean. We just want to defrag the mind.

The main site for the technology, Brain State Technologies™ Brain State Conditioning™.

Imnsho, information like this is an absolute necessity if you don’t want to drown in your own drool. YMMV, of course.
