My favorite bugs are the ones that are too low priority to fix, like this one: https://en.m.wikipedia.org/wiki/Photic_sneeze_reflex The exact pathophysiology is still unknown but it’s a variation on “the nose nerves and the optic nerve are too close together”

The joy of explaining your sneezes every time you see a bright light during cold/flu/pandemic season. I'm surprised to see it affects 20+% of the population because I've never met anyone who knew what I was talking about when I said "sorry, light makes me sneeze"

Ha! I have it too. Doesn't feel like 20% but we're out here

I have extracted this (and other) nerves from cadavers, and this circuitous cranial nerve (XII?) is as beautiful and complex as the multibranch plexus -es (e.g. brachial ). So delicate. Human anatomy, at first glance, often seems wrongly-engineered. After you've worked inside dozens of people, you begin to realize that everybody is unique — and nobody is "textbook" anatomy. Who knows what all this goop even does?! If…

This reminds me of a conversation I was having recently about genetically engineering humans. I think people are greatly underestimating the complexity of the human body and it’s nature mechanisms of adaptation. Everyone is a little different - but that’s okay because all the little feedback loops and receptor sites account for changes. Like a drug addict needing more and more to get their fix. There isn’t just one variable we can adjust to really solve most problems. You have to look at the entire web of interconnected systems and modulate how each of them work together. We sort of take it all for granted since life is so abundant, but it’s truly nothing short of miraculous.

My vagus nerves were constantly being compressed until roughly 4 months ago, when I had bilateral Eagle's syndrome surgeries - Eagle's syndrome a hardening, calcification-ossification of ligaments that connect from the styloid process and wrap around the neck connecting to front of throat; I had played American football for all of high school and most likely the cause from reptitive injuries/trauma to the tissues. We…

My story is very similar. Have had tons of pain and muscle related problems for decades - played a ton of sports like you when i was a kid, and did a lot of physical risk-taking too (skateboarding, bmx-style biking taking them off jump-ramps...) and also had lots of injuries. On top of chronic pain, I had (and still have but is greatly reduced) muscle clenching on the left side of my body - for some reason my body on…

Please don't take this the wrong way but I'm very curious if either of you have heavily modified your diet in an effort to remove part of the pain cycle? A low inflammatory diet might help from my own personal experience with diabolical pain.

It’s interesting you mention “Nobody is textbook anatomy” I know you’re exaggerating for poetic effect but this might actually be true in some parts of the human anatomy. For example the description of the anatomy of vessels and anastomoses around the knee…I have had a professor tell me that the standard anatomical descriptions for this might all essentially be fiction. Basically the variation in some of these vessel…

No, really: nobody has completely textbook anatomy.

Think of it like those blended-face photos. Anatomy books describe that.

I was looking for research papers for the 9 non invasive vagus stimulators I get ads for on instagram. Anyone have success with these for anxiety/depression

Art Of Living’s course 1 Sudarshan Kriya offers breathing course which activates the vagus nerve. I have attended this course. It claims to reduce anxiety, depression and addiction. I have not practiced it regularly. Sorry to say that.

Here is that article:

I hope this helps. I wish you good luck on your journey to good mental health.

Though we have an understanding of what the Vagus nerve does, and I think this article misses that it is involved in both calming and stimulating the para-sympathic nervous system (someone correct me if I'm wrong), but the challenge with any of the "therapies" that apparently stimulate the vagus never is that we can't measure the vagus never directly, and are therefore making assumptions that this is the pathway these therapies are taking.

I had built a "vagus nerve stimulation app" a while back which used vibration to enhance calm. I did some measurements comparing this vibrating stimulation to neurofeedback with a Muse device, and the results seemed positive, but because we couldn't say specifically which mechanism was being triggered, and that it wasn't more than just "listening to calm music", we didn't pursue it.

>> for some reason my body on the left side is clenching up, with this constant pulling on my head, pulling down and to the left. I also have severe TMJ, again on the left, and constant headache

@computerdork do you have a tongue tie/lingual frenulum or narrow airways/diaphragmatic dysfunction? These things can cause extreme issues with the fascia that lead to things presenting in such a manner.

If you’ve made it to teens/adulthood, it’s typically missed by fucking everybody in the medical profession.

Some people wonder why the use of ‘AI’ in pathology is not more effective, and this is part of the reason.
