Figure 9.

Changes in broadband power in source space after practice. (A₁) SAM showing regions of practice-induced increases in total power in all frequency bands at 950–1350 ms after the onset of the second stimulus for all subjects combined. Color bar indicates pseudo F-statistic, image thresholded at p < 0.001. (A₂) Mean normalized power in the left angular gyrus before (black) and after (green) practice among all subjects. (B₁) Event-related SAM showing regions of statistically significant power change during and after the first (0–400 ms) and second stimulus (800–1200). Color bar indicates pseudo F-statistic, image thresholded at p < 0.05. (B₂) Mean and SEM of normalized power in the right auditory cortex before (black) and (after) practice during and after the first and second stimulus.
