Gut & Brain - the Microbiome
« on: September 01, 2020, 02:38:48 PM »
Just curious if anyone out there having gone over Dr. Joe's material has contemplated also that we are not alone in our bodies...

There IS SO MUCH MORE info not only in the article, but also about microbes in general on the internet by science that would astound most of us -  intelligence (as a an "eco-system"), communication, they are found everywhere: in the sea, atmosphere (air), there are some that actually are being utilized to produce gold, & some live in the most hospitable places we would never think of, and they like to gather in groups (colonize) to benefit each other.

Gut-Brain Psychology: Rethinking Psychology From the Microbiota–Gut–Brain Axis

some info from article about them & our body:

Gut microbiota plays a significant role in the host’s mind & behavior, although this role is usually ignored:
First, the gut microbiota regulates pain perception;
Second, cognitive functions, including learning capacity & memory, are closely related to the gut microbiota;
Third, mood and emotion are affected by the gut microbiota;
Fourth, temperament & character are closely linked with the gut microbiota;
Fifth, stress management is impacted by the gut microbiota;
Sixth, gut microbiota affects dietary behavior;
Finally, social interaction & reproductive behavior are strongly linked with the commensal microbiota.

The influences of microbiota overstep the gut & reach the whole body, especially the brain, through the microbiota–gut–brain axis. The microbiota–gut–brain axis mainly contains three pathways: the nerve pathway, neuroendocrine pathway, & immune pathway.

Neurotransmitters
The neurotransmitter content of mammals is regulated not only by their own bodies, but also by their gut microbiota. Gut microbiota can synthesize neurotransmitters directly .

Short-Chain Fatty Acids
Gut microbiota produces short-chain fatty acids (SCFAs), such as acetic acid, propionic acid, and butyric acid, mostly from the degradation of fibers. The SCFAs are recognized by receptors in enterocyte and enteroendocrine cells; thereby, SFCAs further affect the nervous and immune systems. In addition, they can pass the BBB to regulate brain development & neurotransmitter synthesis, thereby impacting the maturation and function of microglia.

Neuropeptides and Neurohormones
Neuropeptides are a type of bioactive peptide that are widespread in the nervous system; they include neuropeptide Y (NPY), oxytocin (OT), calcitonin gene-related peptide, vasoactive intestinal peptide, somatostatin, corticotrophin-releasing factor (CRF) and so forth. These neuropeptides serve as messengers of the microbiota–gut–brain axis and are either released by enterocytes to regulate microbiota or secreted by the microbiota to influence the host.


Melatonin & Circadian Rhythms
Furthermore, circadian rhythms are fundamental properties of mammals, and the microbiota is also regulated by the host’s circadian clock. Melatonin is a neurohormone secreted by the pineal gland that plays a vital role in the regulation of the circadian rhythm. Host circadian rhythms are influenced by bacterial signaling via the immune system, and the gut bacteria are sensitive to melatonin.


Immune Pathway
The immune system plays a crucial role in the symbiotic relationship with commensal microbiota; it has co-evolved with the microbiota for millions of years, and it cannot mature without normal microbial colonization. The absence of the microbiota leads to significant immune deficiency. The gut microbiota regulates the development and function of innate and adaptive immunity and influences neuroimmunity and inflammation to change the brain and behavior.


Most psychological research has omitted the fact that the human being is a superorganism.
The main part of the superorganism is the microbiota, which accounts for more than 90% of the total genes and total cell numbers in the human body. These microorganisms have co-existed with humans for millions of years and play a vital part in the maturation and function of most human organs.

Various aspects of normal psychology, such as pain perception, emotion, cognition, character, stress management, and social behavior, are impacted by the gut microbiota. Microbiota disturbance can be induced by many factors, including stress, antibiotics, and unhealthy diet, and it could be a direct cause of mental illnesses.


here's a catchy title to another interesting article:

Thanks for this, I read the last article and it's very interesting! I believe it would be in line with what Joe Dispenza says, but maybe a bit outside of his scope?

I read The Longevity Paradox, which goes into the good and bad chemicals deposited in the body as by products of the gut biome we encourage by what we feed them via our diets. I do need to lay off the carbs, not at all encouraging the “gut buddies” to thrive.
