Fig. 5. Augmentation increases EJP amplitudes during various gastric mill-like stimulations. (A) Comparison of the amplitudes of the first EJPs of the first (white bars) and the tenth stimulus train (black/gray bars) during ion, dpon, weak in vivo, intermediate in vivo and strong in vivo rhythms. Average of N=6 animals. (B) Comparison of the amplitudes of the last EJPs of the first (white bars) and the tenth stimulus train (black/gray bars) during ion, dpon, weak, intermediate and strong rhythms. (C) Plot of augmentation index A (as revealed from the normalized first EJP of the tenth stimulus train) over train number. A is shown for ion and dpon rhythms. (D) Plot of augmentation index A of the first EJP over train number for weak, intermediate and strong in vivo rhythms. (E) Plot of augmentation index A of the last EJP over train number. A is shown for ion and dpon rhythms. (F) Plot of augmentation index A of the last EJP over train number for weak, intermediate and strong in vivo rhythms.
