Cold stress inhibits gastric motor activity. The purpose of this study was to use the surface‐recorded electrogastrogram (EGG) to determine what characteristics of the gastric myoelectric activity accompany this decrease in gastric motor activity. Thirty fasted healthy male volunteers participated in the study. Twelve remained fasted and placed their hands in 4°C ice water (cold stress), 12 ate a meal and then underwent cold stress, and 6 control subjects ate and then put their hands in 30°C… Expand

TLDR
Investigation of gastric myoelectrical activity and vagal activity in response to stress found stress has an inhibitory effect on postprandial GMA and this may involve both vagal and sympathetic pathway. Expand
Inhibitory effects of various types of stress on gastric tone and gastric myoelectrical activity in dogs
TLDR
Cold- and audio stress inhibit gastric tone and impair gastric slow waves, whereas visual stress does not seem to have such effects, to increase the understanding of gastrointestinal motor disorders related to stress. Expand
Alteration of gastric myoelectrical and autonomic activities with audio stimulation in healthy humans
TLDR
Investigation of the effects of music or noise on gastric myoelectrical activity and autonomic function in healthy volunteers found classical music seems to increase bradygastria, whereas, household noise may increase arrhythmia. Expand
The effect of autonomic nervous system activity on gastric myoelectrical activity: does the spectral reserve hypothesis hold for the stomach?
TLDR
It was concluded that: (1) tasks that alter ANS activity do systematically alter gastric myoelectrical activity; and (2) gastricMyoelectedrical activity does not follow the cardiac model of health being associated with increased spectral complexity. Expand
Gastric myoelectrical and autonomic cardiac reactivity to laboratory stressors.
TLDR
It is demonstrated that laboratory stressors concurrently affect gastric myoelectrical activity and autonomic control of the heart, and that stressor-induced decreases in RSA and higher levels of somatization predict motion sickness susceptibility. Expand
Gastric Dysrhythmias and Transient Sleep Impairment in Healthy Subjects
TLDR
The study provides a potential clue that transient sleep impairment might influence gastric myoelectrical functioning in healthy individuals and indicates that impaired sleep quality is associated with increases in gastric dysrhythmia and altered perception to gastric distension in response to the water load. Expand
Effect of public speaking on gastric myoelectrical reactivity and parasympathetic cardiac control
Gastrointestinal reactivity is a central concept in several psychosomatic approaches to peptic ulcer disease and irritable bowel disease. One potential limitation of many laboratory studies ofExpand
Gastric myoelectrical activity in premature and term infants
TLDR
EGGs may be recorded successfully from preterm and term infants, postprandial gastric myoelectrical activity in all frequency bands is similar among groups of premature andterm infants, and gavage feedings in premature infants did not increase 3 cpm EGG activity. Expand
Association of heart rate variability, blood pressure variability, and baroreflex sensitivity with gastric motility at rest and during cold pressor test
TLDR
EGG frequency can be decreased by an acute increase in sympathetic activity induced by CPT and the novel findings are the significant correlations between many of the HRV, BPV, and BRS parameters and EGG frequency. Expand

TLDR
Although enteral feeding is important for the development process of gastrointestinal motility, gastric electrical activity and gastric emptying show an intrinsic maturation depending on the gestational age. Expand

Perturbation of upper gastrointestinal function by cold stress.
TLDR
The findings show that the normal postprandial function of the upper gut can be measurably disturbed by a stressful stimulus, and the coincidence of these disturbances with other extra-intestinal autonomic changes suggests that they are a further manifestation of the somatic response to a stress. Expand
Stress-induced gastroduodenal motor disturbances in humans: possible humoral mechanisms.
TLDR
It is concluded that centrally acting external stimuli may severely disrupt antral feeding activity and concurrent elevations in plasma levels of beta-endorphin and norepinephrine raise the possibility that these substances may be involved as mediators of the central effects on the gut. Expand
Gastroduodenal motility during the delayed gastric emptying induced by cold stress.
TLDR
It is concluded that in addition to the previously reported antral inhibition, cold stress is associated with changes in pyloric and duodenal motility and, in some subjects, in the intragastric distribution of food. Expand
Neuroendocrine and gastric myoelectrical responses to illusory self-motion in humans.
TLDR
Examining gastric myoelectrical activity and endogenous neuroendocrine responses in subjects with and without motion sickness elicited by illusory self-motion or vection concluded that vection stimulates brain-gut interactions, resulting in gastric tachyarrhythmias and complex neuroendocrin responses inSubjects with motion sickness.

Spectral analysis of tachygastria recorded during motion sickness.
TLDR
Running spectral analysis revealed a close correspondence over time between tachygastria and reports of symptoms of motion sickness. Expand

Gastric Myoelectric Activity in Patients with Chronic Idiopathic Gastroparesis
TLDR
In patients with chronic idiopathic gastroparesis a large variety of electric arrhythmias ranging from premature control potentials to tachygastria, tachyarrhythmia, bradygastsria, and bradyarrhythmmia and to a complete disorganization of electric control activity were recorded. Expand
Effect of opiate and adrenergic blockers on the gut motor response to centrally acting stimuli.
TLDR
The results suggest that opioids and catecholamines are involved in the mediation of the disruptive effects induced by centrally acting stressful stimuli on postprandial motor activity in the proximal human gut. Expand
Experiments and Observations on the Gastric Juice, and the Physiology of Digestion
TLDR
The subject upon which the experiments of the latter were performed was a young man, of a good constitution, robust and healthy, who was accidentally wounded by the discharge of a musket loaded with buck-shot on the Gth of June, 1822. Expand
HUMAN GASTRIC FUNCTION
TLDR
This film presents an unusual case, illustrating only a few of the studies and experimental methods which have been reported by the author and published in book form, and compares the patient with Alexis St. Martin, whose fistula was the object of the well-known scientific observations of Colonel Beaumont more than a hundred years ago.
