Differences in the activation extent in the seed regions of the functional connectivities.

<p>(A) Clusters showing the differences in activation extent are in red, and the seed regions for the functional connectivities are in yellow. (B) The parametric estimates of these clusters showing the differences in activation extent during each task condition are also shown.

Activated regions across the four conditions obtained by conjunction analysis.

<p>The activated regions are shown in red. For the presentation purposes, a threshold of p<0.01 (corrected by FDR) was used. The seed regions for functional connectivity are shown in purple.

The mean r-value matrices (A) and hierarchical clustering analyses (B) for the four task conditions: the preferential choice in the gain domain, the preferential choice in the loss domain, the trade-off instruction choice in the gain domain and the trade-off instruction choice in the loss domain.

<p>(A): Each figure shows a 19×19 square matrix in which the x and y axes correspond to the regions listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041048#pone-0041048-t001" target="_blank">Table 1</a> and in which each entry indicates the mean strength of the functional connectivity between each pair of brain regions. The z score of the functional connectivity is indicated with a colored bar. (B): The vertical axis represents distance. The numbers in the horizontal axis represent the seed regions.

Seed regions for the interregional functional connectivity analyses.

*<p>Seed regions were generated from 12-mm diameter spheres centered on the peak foci of the region. The other seed regions were generated from 18-mm diameter spheres centered on the peak foci.
