Reduced Risk-Taking following Disruption of the Intraparietal Sulcus.

ABSTRACT: Decision makers frequently encounter opportunities to pursue great gains-assuming they are willing to accept greater risks. Previous neuroimaging studies have shown that activity in the intraparietal sulcus (IPS) and the inferior frontal junction (IFJ) are associated with individual preferences for economic risk ("known unknowns," e.g., a 50% chance of winning $5) and ambiguity ("unknown unknowns," e.g., an unknown chance of winning $5), respectively. Whether processing in these regions causally enables risk-taking for individual decisions, however, remains unknown. To examine this question, we assessed the decision to engage in risk-taking after disrupting neural processing in the IPS and IFJ of healthy human participants using repetitive transcranial magnetic stimulation.
