The amplitudes of the first EJP of the first stimulus train are compared to the amplitudes of the first EJP of the tenth stimulus train. Similarly, the amplitudes of the last EJP of the first stimulus train are compared to the amplitudes of the last EJP of the tenth stimulus train.

Significance (P) refers to the difference between first and tenth stimulus trains.

NS, not significant.
