Researchers at Yale School of Medicine have found that the volume of the parietal cortex in the brain could predict where people fall on the risk-taking spectrum.<\/p>\n<p>Led by Ifat Levy, assistant professor in comparative medicine and neurobiology at Yale School of Medicine, the team found that <strong>those with larger volume in a particular part of the parietal cortex were willing to take more risks than those with less volume in this part of the brain<\/strong>. The findings are published in the Sept. 10 issue of <em>The Journal of Neuroscience<\/em>.<\/p>\n<p>Although several cognitive and personality traits are reflected in brain structure, <strong>there has been little research linking brain structure to economic preferences<\/strong>. Levy and her colleagues sought to examine this question in their study.<\/p>\n<p>Study participants included young adult men and women from the northeastern United States. Participants made a series of choices between monetary lotteries that varied in their degree of risk, and the research team conducted standard anatomical MRI brain scans. <strong>The results were first obtained in a group of 28 participants, and then confirmed in a second, independent, group of 33 participants<\/strong>.<\/p>\n<p>&#8220;Based on our findings, we could, in principle, use millions of existing medical brains scans to assess risk attitudes in populations,&#8221; said Levy. &#8220;It could also help us explain differences in risk attitudes based in part on structural brain differences.&#8221;<\/p>\n<p><strong>Levy cautions that the results do not speak to causality<\/strong>. &#8220;We don&#8217;t know if structural changes lead to behavioral changes or vice-versa,&#8221; she said.<\/p>\n<p>Levy and her team had <strong>previously shown that risk aversion increases as people age, and we scientists also know that the cortex thins substantially with age<\/strong>. &#8220;It could be that this thinning explains the behavioral changes; we are now testing that possibility,&#8221; said Levy, who also notes that more studies in wider populations are needed.<\/p><\/blockquote>\n<p>The study was a collaboration of researchers from Yale, University College London, New York University, University of Pennsylvania, and the University of Sydney, Australia. In addition to Levy, authors include Sharon Gilaie-Dotan, Agnieszka Tymula, Nicole Cooper, Joseph W. Kable, and Paul W. Glimcher.<\/p>\n<p>The study was funded by the National Institute of Aging (R01AG033406).
