Close your eyes and think about your favorite food. Maybe salt and chips? Now scan your body to see what changes have taken place. Have you drooled? Or do you think you are hungrier than before? This is a perfect example of the role of our central nervous system in the intestinal nervous system(the reticular nervous system that controls gastrointestinal function). This specific example – as Alessio Pasano and Susi Prahti described in their online books, “stomach sensation” is Pavlovian reaction- This means that external stimuli produce internal responses, such as the sound of words. This part of the gastrointestinal brain axis is easy to understand, so it is widely understood and accepted. Think about it! We can feel a new occupation every day, whether we are hungry after hearing the word pizza or can’t eat food on the first day. It’s all about the role your brain plays. This correlation is also very clear in the incidence rate of gastrointestinal diseases, which is incredible. Irritable Bowel Syndrome(IBS) refers to short-term and neurological diseases, such as anxiety or depression; this may be caused by social factors or personal behaviors or thinking patterns(Fasano et al., 2021).

What is more difficult to understand is that what has just been studied is how the gut brain axis works in reverse. This means that the enteric nervous system can affect the central nervous system in the same way. Pioneers in the field of psychology first collected a lot of research, associating enterobacter with autism spectrum disorder, anxiety disorder, epilepsy, Parkinson’s disease and other neurological diseases(Fasano et al., 2021). All people suffering from this disease have one thing in common, that is, the gastric microbiome lacks biodiversity(Bastiaansen et al., 2020). To further study the concept that gastrointestinal affects the central nervous system through the use of probiotics and probiotics. First, let’s define what Provices and Provices are. Probiotics are microorganisms that promote intestinal health and can be found in yogurt or fermented foods. Prebiotics are a kind of food particles that are not easy to digest, which can promote the host to produce beneficial bacteria in the colon for digestion. Studies have shown that in order to treat I.B.S., the anxiety symptoms of participants taking biological agents have also been greatly improved(Bastiaansen et al., 2020).

In contrast, there are about 500 different microbial communities in the gastrointestinal tract. This is 10 times the number of white blood cells in our body(McEwan et al., 2019). Some experts believe that the close relationship between gut and brain can be traced back to our development stage. Pertaining to the ectoderm(one of the three germ layers of an embryo), the place where G.I. islands and the brain form. This may lead to the close function or communication of hormone signals, neural networks and endocrine signals between these two body systems(Fasano et al., 2021)

In conclusion, for the above reasons, the importance of the two systems cannot be denied. The next time you consider buying fast food instead of preparing a meal properly or not eating a meal, think about the main roles played by these two people in each other. This may be the difference between an efficiency day and a bad day.
