William Beaumont's monograph on the physiology of digestion which was first published in 1833, has become a classic in its field. In a series of experiments over a 10 year period on Alexis St. Martin, a 19 year old Canadian voyageur with a traumatic gastric fistula, Beaumont was the first to describe many important aspects of the digestive process. In two of the 238 experiments Beaumont noted gastric physiological changes induced by emotional arousal, these being bile reflux and delayed gastric…

History of Development of Gastrointestinal Physiology: From Antiquity to Modern Period and the Birth of Modern Digestive Physiology
This chapter provides contemporary information on the historical timeline of events that transpired on GI physiology beginning from antiquity to the contemporary period to allow for meaningful future investigations that could fetch the world results for the betterment of life.
Effects of occupational stress on the gastrointestinal tract.
The identification, stratification, measurement and evaluation of stress and its associated corrective strategies, particularly for occupational stress, are important topics to address in the near future to establish the basis for considering stress as an important risk factor in occupational health.
Gastrointestinal Motor Function
This chapter aims to identify the course and key milestones in GI motility research and lays down basic concepts and principles of motility of different regions of the gut and their relationship to the maintenance of the functioning of digestion.
Dickdarmmikrobiom und Depression
Combining gut microbiome analysis with observations on the hypothalamus-pituitary-adrenal axis and various aspects of inflammation helped to gain first insights into the role of the microbiota-gut-brain-axis in depressive disorders.

Beaumont was the first to document the inhibitory effects on digestion by direct observation of the stomach by identifying neuronal pathways and humoral mechanisms responsible for the phenomena.
A Study of an Infant With a Gastric Fistula: I. Behavior and the Rate of Total Hydrochloric Acid Secretion
The results support the psychoanalytic concept that, at this level of development, the establishment of object representations involves an oral, intaking model and lend support to the concept of an oral stage of development.
Studies on the Experimental Evocation of Depressive Responses using Hypnosis: III. The Secretory Rate of Total Gastric Acid with Respect to Various Spontaneous Experiences such as Nausea, Disgust, Crying, and Dyspnea
The group results revealed a consistent association between the direction of the secretory rate of total gastric acid and the coincident phenomenological experience irrespective of whether or not the subjects were hypnotized.
Studies on the Experimental Evocation of Depressive Responses Using Hypnosis: II. The Influence of Depressive Responses Upon the Secretion of Gastric Acid
The design was shown to provide a reliable method for the differential evocation of affective responses experimentally and a positive correlation between the secretory rate of total gastric acid and the coincident dominant affective response was demonstrated.

The Irritable Gut
The irritable gut is what is left when no organic explanation for gut symptoms can be found and the aim in diagnosis is to identify or exclude pathology.
