The cortical volume of a region in posterior parietal cortex is predictive of individual risk attitudes. Top: exploratory analysis revealed a significant positive correlation between the volume of the highlighted region (left) and risk tolerance (right) in a group of 28 individuals. Bottom: the result was confirmed in an independent group of participants, using a different scanner and a different behavioral task to estimate risk attitudes. Gray matter volume in the same region significantly predicted risk tolerance (p < 0.05; left), while the volume of a control region in the vicinity of the primary motor/somatosensory cortex was not predictive of risk attitudes (right).
