Fig. 4.
ROI time courses separately for SMAup/PHCdown and SMAdown/PHCup blocks of the last training runs. SMA activity (green) was increased during SMAup/PHCdown blocks (solid lines), and decreased during SMAdown/PHCup blocks (dashed lines). In contrast, PHC activity (blue) was decreased during SMAup/PHCdown blocks, and increased during SMAdown/PHCup blocks. This illustrates that successful self-regulation was accomplished by up- and down-regulating the respective ROI. Shaded areas represent one standard error of the mean. The time courses were normalized so that the percentage of signal change during baseline activity corresponded to 0%.(For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
