The phenomenon of the gut–memory connection is based on and part of the idea of the gut-brain axis, a complex communication network, linking the central nervous system to the gut. The gut-brain axis first gained significant momentum in research and formal recognition in the 20th century with advancements in neuroscience and gastroenterology ...
The gut–brain axis is the two-way biochemical signaling that takes place between the gastrointestinal tract (GI tract) and the central nervous system (CNS). [2] The term "microbiota–gut–brain axis" highlights the role of gut microbiota in these biochemical signaling.
[4] [3] [6] [8] It is most abundantly found in the brain and to a smaller extent in other tissues, such as the gut and heart. [6] Under pathological conditions in PD, alpha-synuclein undergoes a conformational change, resulting in a misfolded insoluble protein that aggregates into beta-sheets and forms protein inclusions called Lewy Bodies .
The intestine is also called the bowel or the gut. The lower GI starts at the pyloric sphincter of the stomach and finishes at the anus. The small intestine is subdivided into the duodenum, the jejunum and the ileum. The cecum marks the division between the small and large intestine. The large intestine includes the rectum and anal canal. [2]
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
The mammalian nervous system is arranged with the neural tube running along an anterior to posterior axis, from nose to tail for a four-legged animal like a dog. Humans, as two-legged animals, have a bend in the neuraxis between the brain stem and the diencephalon, along with a bend in the neck, so that the eyes and the face are oriented forward.
The connectogram, as a graphical representation of brain connectomics, was proposed in 2012. [1]Circular representations of connections have been used in a number of disciplines; examples include representation of aspects of epidemics, [2] geographical networks, [3] musical beats, [4] diversity in bird populations, [5] and genomic data.

Notochord is positioned just ventral to the neural tube and dorsal to the gut, flanked by myotome. (D) Notochord homolog in annelid. Cross-section showing the position of the proposed axochord to the ventral mesentery, blood vessel, and nerve chord. Axochord is found to be dorsal to the nerve chord and ventral to gut of the animal.
