Fig. 8. Intestinal pre-retrograde giant contraction (RGC) inhibition of myoelectric activity. This figure depicts the intestinal myoelectric response (EI) recorded from the same site as the strain gauge (SG) at 50 cm from the pylorus. Note that the electrical control activity (ECA) becomes disrupted, ie, ceases to occur (indicated by the downwards arrow), about 5 seconds before the start of the RGC, and that the RGC potential occurs at the upstroke of the RGC.
