UZH researchers find new measure to predict stress resilience


 E-Mail
Researchers at the University of Zurich show that increased sensitivity in a specific region of the brain contributes to the development of anxiety and depression in response to real-life stress. Their study establishes an objective neurobiological measure for stress resilience in humans.
Some people don t seem to be too bothered when it comes to handling stress. For others, however, prolonged exposure to stress can lead to symptoms of anxiety and depression. While stress resilience is a widely discussed concept, it is still very challenging to predict people s individual response to increased levels of stress. Lab experiments can only go so far in replicating the chronic stress many people experience in their day-to-day lives, as stress simulated in the lab is always limited in exposure time and intensity. ....

Risk-taking linked to particular brain features


 E-Mail
Risky behaviors such as smoking, alcohol and drug use, speeding, or frequently changing sexual partners result in enormous health and economic consequences and lead to associated costs of an estimated 600 billion dollars a year in the US alone. In order to define measures that could reduce these costs, a better understanding of the basis and mechanisms of risk-taking is needed.
Functional and anatomical differences
UZH neuro-economists Goekhan Aydogan, Todd Hare and Christian Ruff, together with an international research team looked at the genetic characteristics that correlate with risk-taking behavior. Using a representative sample of 25,000 people, the researchers examined the relationship between individual differences in brain anatomy and the propensity to engage in risky behavior. We found both functional and anatomical differences, says Goekhan Aydogan. ....
