Activation volume and overlap of neighboring activation clusters extracted from the first session. A Average (large colored circles) and individual (small black circles) activation cluster volumes. D1 and D2 generally occupy the most space while the other three digits (D3, D4, and D5) have smaller activation volumes. This general pattern can be observed both for TW and BD. B Average (large two-colored circles) and individual (small black circles) measures of activation overlap between two neighboring activation clusters. There is a nonsignificant trend towards more overlap in the TW design as compared to the BD. Error bars represent the standard error of the mean
