    Abstract:
    In 62 normal males and females gastrointestinal (GI) electrical activity was evaluated before and after standard breakfast with the method of epicutaneous electrogastroenterography (EGEG) with the use of AgCl electrodes and original hard- and software "Gastroenterograph" developed by the authors. Spectral analysis (SA) of GI electrical potentials enabled quantification of the electrical activity of the stomach, duodenum, jejunum, ileum and the whole of the small intestine. The stomach and the small intestine were main contributors to the total GI electrical activity during fasting. Changes in the functional activity of the digestive system after the meal were characterized by increases in selected SA parameters (length of the spectral curve and area underneath), dissociation between their values and redistribution of ratios in different GI segments.
