According to a study, people with a stronger connection between two specific brain regions have a more cautious financial outlook.

The researchers studied the connections between two brain regions - known as the anterior insula and nucleus accumbens - and how the two work together.

Participants were given USD 10 that they could gamble or not. Entering an MRI chamber, they could see a roulette wheel and the odds for winning or losing.

In one bet, they had equal odds to win or lose USD 3. In another, they had higher odds of winning a smaller amount and small odds of losing a lot or vice versa.

As the participants weighed the various gambles, the researchers tracked activity in the two brain regions. The findings revealed that even the cautious ones with a well-insulated connection would sometimes place risky bets.

And when they did, the more cautious region stayed quieter while the enthusiastic region grew more active.

"The study helps scientists and policymakers who want to better understand risky decision-making in the context of gambling and addiction and develop more effective interventions," noted the authors in a paper that appeared in the journal Neuron.
