Since the frequency and the originally generated amplitude of this broad-spectrum rectangular signal are known, it is possible to quantify its amplitude attenuation and related modulation by measuring the resultant signal at the surface of the skin using a plain electrogastrograph [16].
The cutaneous electrodes were connected to a custom-designed multichannel electrogastrograph (EGG, James Long Company, Caroga Lake, NY, USA), which measured the surface electrical activity relative to ground.
Using an electrogastrograph, an external electrical monitoring device that is to the stomach what the electrocardiograph is to the heart, he and his colleagues at Ohio State University in Columbus have been able to measure the "butterflies." The technique is also being used to study other conditions, among them motion sickness, which Pennsylvania State University researchers have linked to erratic electrogastrograms (EGGs).
