components in the rank from sti to fini (defined by received investigated range of this organ of GI tract) by Discrete Fourier transform of the electric signal from GI tract. PS – the general (total) capacity of an electric signal from five parts of GI tract: P(i)/PS – the relative electric activity. Kritm(i) – rhythm factor EGEG parameters for normal patients: Psychological applications Psychologists have performed psychophysiological studies to see what happens in the body during affective experiences. Electrogastrograms have recently been used to test physiological arousal, which was already determined by measures such as heart rate, electrodermal skin responses, and changes in hormone levels in saliva. Currently, a pattern of interest to psychologists is an increase in bradygastria, which is when electrical activity in the stomach drops to below 2 cpm resulting in a slower stomach rhythm, when exposed to disgusting stimuli, which may be a precursor to nausea and vomiting, both physiological responses to disgust. In this study, the presence of bradygastria was able to predict trait and state disgust, which no other physiological measure used in the study was able to detect. This abnormal myoelectrical activity is usually combined with other precursors to nausea and vomiting, such as increased salivary production, which further supports the idea that these rhythms show early signs of nausea and vomiting. These reactions are viewed as a way in which the body rejects unhealthy foods, which is linked with the view that disgust is an evolutionary adaptation to help humans avoid consuming toxic substances. During sham feeding sessions of both appetizing and unappetizing foods, 3 cycles per minute (cpm) power was measured. During the sham feeding of appetizing foods, 3cpm power increased. This increase was not reported in the sham feeding of unappetizing foods. The researchers concluded that the presence of this pattern seems to mark the beginning of the body preparing for digestion, and the absence of this pattern in the disgust condition could indicate that the body is readying to reject the food. The increase of 3cpm power is also linked with increased saliva and digestive juice production, all of which support the idea that this reflex, called the cephalic-vagal reflex, is the precursor of digestion. The differential response to appetizing and unappetizing foods suggest that the body uses disgust as a cue to whether a food is good to eat and responds accordingly.
