This is definitely a very interesting article. It is fascinating to know that there is a powerful link between the human brain and gut bacteria. It is of huge interest to see how science has been able to show that the digestive tract and the brain are crucially linked, according to mounting evidence showing that diet and gut bacteria are able to influence our behavior, thoughts and mood. For example, studies have shown that healthy students present in their stool large amount of Lactobicillus during a high-stress exam time compared with a less stressful period during the semester. The findings suggest a potential link between stress and gut microbes, but the exact relation remains unknown. Also it has been shown that healthy human volunteers who consumed a probiotic mix containing Bifidobacterium Longum exhibited less anxiety and depression. I remember once, reading an article stating that there is laboratory evidence that indicates that H. pylori cells can escape the gut and sneak into the brain. There the cells aggregate with the amyloid proteins characteristic of Alzheimer's and instigate the buildup of plaque, contributing to the symptoms of Alzheimer's. All this evidence based medicine may lead to the development of new innovations like bacteria laden broth or fecal transplant; with the may serve as new options for the treatment of psychiatric conditions such as depression or anxiety. This is even more important when 50% of the neurotransmitter like dopamine and serotine, originate from the gut flora, that way we use the bodies on natural products to help treat mental illnesses.

This article presents findings that may seem unlikely and completely unrelated to a common eye. It is truly impressive how the GI system and the central nervous system have such a strong connection. However, these findings make complete sense. The body is a factory, and our organ systems are departments. The GI system is a distribution center of raw material, that the body needs to fuel itself and carry on even the most minuscule function. So in that sense, why wouldn't there be such a connection and influence? Nevertheless, I think it is easy to forget how the GI system also houses a great community of microbiota. Therefore, it is not just the GI's masterpiece to supply these NTs - it's the bacteria who are the main players in the equation. I think that these findings suggest new questions and hypothesis. For example, all microbiotas may not be the same. For instance, it may vary regionally, and so, the microbiota distribution could have a correlation with the prevalence of depression and anxiety in said region or social group. For example, if processed foods exert a role in our GI systems and could potentially remodel our GI microbiota, would this mean that ingestion of processed foods has an impact in further development of said conditions? Borchard (2015) discuss a study by John Cyran, in which 2 varieties of Bifidobacterium produced in a lab were more effective than Lexapro (an SSRI, i.e. the first line treatment for depression) in treating anxiety and depression.

According to Lyte, single celled organisms could influence our neural circuitry. Bacteria in our gut (gut flora) is important for many meaningful processes such as fermenting unused energy substrates, training the immune system , preventing growth of harmful, pathogenic bacteria, and also producing vitamins such as biotin and Vitamin K. The presence and absence of these bacteria has been linked to many illnesses. Research has shown small amounts of evidence that anxiety, depression, and many pediatric disorders such as autism and hyperactivity are linked to gastrointestinal abnormalities. Lyte found that microorganisms in the gut secrete dopamine, serotonin, and GABA. Several researchers have explored the topic, of the interaction microorganisms with neurological function.
