Figure 4. Cross-subject correlation results.

(A) The rACC that showed negative correlation between bet size changes and neural activation change as a function of prior outcome was overlaid on an axial slice of the group mean structural image. For display purposes, the activation map was shown at Z>2.3. (B) Scatter plot of the correlation. Please note the scatter plot is only used to check possible outliers. The correlation coefficient should be treated cautiously due to the double-dipping issue.
