Comparisons of brain activation between extrapunitive and intropunitive individuals in the ego-blocking condition.

Extrapunitive individuals showed greater activation in the bilateral ventrolateral prefrontal cortex than intropunitive individuals. On the other hand, intropunitive individuals showed greater activation in the left dorsolateral prefrontal cortex than extrapunitive individuals. Brain images were the templates embedded in the SPM, and its usage was permitted for a non-profit purpose.
