Figure 2. Effects of repetitive megnetic stimulation on the amplitude of waves.
A, effects of rTMS on the mean amplitude of the I1 wave in individual subjects (dashed lines), the continuous line represents the mean from the same subjects. Error bars indicate standard deviations. rTMS has a pronounced effect on the amplitude of the I1 wave (F3,9 = 9, P < 0.005). B, effects of rTMS on the mean amplitude of later I waves.
