i like how this research (and others related) kind of supports the idea that free will might be lacking. I still keep a pinch of skepticism about this idea, understanding that it's just a concept. But personally i like it, because it even fells a bit relieving... not to say that it helps you abandon responsibility, but it makes your stance on life easier, and pushes you not to blame yourself too much for your weaknesses.

#32Everyone's "poo-pooing" the article because the title doesn't mention mice, but, FWIW, stories of gut biota affecting humans behavior have been documented for a while. Memory gain is noteworthy, which is the article's "wow" factor, but everyone's just knee-jerk smirking so ... here's a few random articles to gross you out about the wild world of trading microbiota and, for better or worse, changing your personality:…
I would recommend the site https://gutbrainaxistherapeutics.com for learning more about Microbiota Transplant Therapy (MTT) and its opportunities, especially for Autism and Pitt-Hopkins Syndrome.
I’ll dig in more but my first question when I see this: who are the donors exactly? Like who decides what the ideal gut microbiome is and that John Doe is the guy to provide his fecal matter to the masses?

#34IMO people should eat more fiber. A lot more fiber. It cleans the gut, the liver, absorbs cholesterol, slows insulin response and makes you feel full longer. The microbes in our guts need it to function. Rather than jumping from one fad diet to another, just eat what you like and be sure to get a lot of fiber each day.
To do this eat stuff that grows and not further processed.

Agreed, but I think the mechanism relates to different microbes. If there are two microbes in your gut, and type A requires a dose of high-calorie, low-fiber food coming down the pipe every day, and type B is not able to reproduce as fast as type A but is able to live on high-fiber food, this tells you two things:
type A cannot have been living in humans thousands of years ago, but type B might have
type A benefits from making your brain worse at choosing healthy foods, and type B does not
Which kind would you rather have in your gut?

#36I got into bicycle touring a few years ago, and it’s an ultra-endurance activity which means burning 3- 4 times as many calories as I would on a sedentary day. My training rides were all local weekend overnighters in preparation for the big 1000 mile challenge ride, and they were no big deal.
On the big ride, about 3 days in I started experiencing bouts of intestinal distress which would put me into some of the blackest moods I can recall experiencing as an adult. My whole thought process broke down and I became ruthlessly nihilistic about everything. I was ready to tell my partner to go fuck himself, chuck my bike off a bridge and take an uber to the nearest airport.
But then when the intestinal distress subsided I came back to my senses and I was like “WTH was that all about?” It happened several times, to varying degrees of intensity over the 10 day tour. My eating strategy improved and I bought some cannabis which helped my manage the issue and I was able to complete the tour.
That was a few years ago and I’ve never experienced the black mood again. It has prompted me to believe that the mind-gut connection is much stronger than we might have been giving it credit for, and if you suffer from mood or cognition issues, big or small, you may want to investigate whether your guts and gut flora might be playing an influential role.

I believe this research is totally true-- I had a lot of memories come back after 1. I stopped drinking heavily and using other drugs, i.e. marijuana 2. managed my diet to avoid heartburn without medication 3. schedule my meals so it was easier to sleep at night (always eat something for breakfast when I wake up) I did not need any "poo infusion" or anything.

Your hypothesis here though is full of complicating factors.
For example
>I stopped drinking heavily and using other drugs, i.e. marijuana
Like the primary change you made was to cut out using a whole bunch of drugs with known, significant neurological effects.

#38Yeah, it's a mouse study, but there are tons of human studies backing the whole gut-brain connection. There are even a bunch of books on it [1][2]. What's really cool is that the paper used low-dose capsaicin (just 5 μg/kg injected), and it completely restored hippocampal FOS activity and memory in older mice. Basically, that's the same stuff you get in cayenne pepper supplements - pretty easy to get your hands on. […
I've long regarded the great variety of chilis as its own distinct food group. But wonderful as they are for flavoring food, quite often in my home, I'm not sure how much of an effect orally consumed capsaicin has on memory functioning.
Conceivably parenteral capsaicin has different effects on hippocampal integrity or physiology than achievable with ingestion. I'm not familiar enough with disposition of capsaicin in the gut to comment further. My question is whether capsaicin passes from gut into the circulation in any appreciable quantity. I suspect it doesn't but I couldn't say I know for sure. I'll have to add it to the already long list of things I need to look up.

This seems to be a recent anti-science meme to dismiss studies that use mouse models. I'm sure there is an interesting line of discussion about the strengths and limits of those models, but that's probably a complex, nuanced thread to pull, not something you blow off with a hand-waving internet comment.
It's not anti-science, it's anti-science-journalism-hype.
Science depends on accurately reporting facts, being clear about the limits of your findings, and seeking explanations that survive scrutiny. Science journalism has other priorities that are often in conflict with those of science.

What did you do for heartburn? Just looking for ideas. I noticed reducing gluten helped me personally a lot
not the commenter but I bake my own soda bread and found that i was getting heartburn from the salt that was in the recipe. once i eliminated that i could eat as much as i wanted. I also cannot eat salt preserved potato chips on consecutive days.
