IN most of those diseases where emotional states are thought to be etiologically related to focal or systemic lesions, it is generally assumed that the pathologic process is mediated by the autonomic nervous system and the humoral mechanisms under its control. There is considerable experimental and clinical evidence to support such an assumption. But little information has accumulated to indicate by what mechanism the emotions can so act on autonomic centers as to lead to diseases as diverse as… 
The Limbic System and Stress Ulcers
Our working hypothesis, over the past decade, has been that the limbic system modulates stress ulcer susceptibility1,2. It was largely based on early reports in the literature that linked (in a vague

Whereas in preindustrial cultures the major agencies of disease are parasitic, nutritional, and infectious, in advanced industrial societies emotional agencies emerge paramount and the need to attain a workable general definition of emotion is particularly pressing.
Ethological Foundations of Biological Psychiatry
It is proposed that only an approach based on evolutionary biology and a comparison of species, i.e. on an ethological approach, can lead to a neurobiological explanation of the normal and pathological states mentioned by Hippocrates.

The limbic system has been linked to so-called psychosomatic disorders for decades. In fact, MacLean’ coined the term “visceral brain” to describe a system of structures that included the amygdala,

Psychosocial Factors, Psychiatric Illness and Functional Gastrointestinal Disorders: A Historical Perspective
It is concluded that a lot of the knowledge that became available recently through modern research methodology can also be found in the historical psychosomatic and neuroscience literature, though obviously less empirically grounded, which provides further support for an integrative, multidisciplinary biopsychosocial approach to FGID.
Evolutionary Biology of Emotion
The idea that evolutionary considerations may aid in the understanding of mental processes in both healthy and diseased states has a long history, but has now receded into the background because of
The visceral brain of man.

While it has long been known that visceral symptoms such as pallor, salivation and epigastric distress may herald or accompany an epileptic seizure, these symptoms cannot be regarded as having any localizing value unless a focal brain lesion is proved to be their cause.
Neurobiological Basis of Emotions
Dysfunction of these circuits has also been related to a range of behavioral and neuropsychiatric problems, with the orbitofrontal cortex being the focus of recent research interest.
