INTERVAL One voltage series was made when the interval between stimuli was 100 msec. In Fig. 7 are represented the results obtained. It can be seen that at 2 volts there was no modification; at 3 volts the negative potential began to decrease and the positive one remained unchanged. At 4 and 5 volts the dimniution of the negative potential was more marked and no change was observed on the positive 2v 3v 4v 5v Fig. 7 Voltage series at

Calibration: 500 [iV. VOLTAGE SERIES AT 50 MSEC. INTERVAL The same voltage series was repeated at 50 msec, interval between stimuli and the results arc summarized in Fig. 8. It can be observed that at 2 volts there is already a decrease oi the negative potential which is more marked at 3 and 5 volts. Regarding the positive wave a little increase was seen. In all the previous experiments the negative wave underwent significant changes, while the positive wave remained almost unchanged. Only when.
