Electrode-mediated analysis of brain activity in 10 individuals with epilepsy that was carried out while the individuals played a computerized gambling game revealed that the individuals exhibited increased high-frequency activity in the brain's right hemisphere when they were biased toward placing risky bets and increased high-frequency activity in the brain's left hemisphere when they were biased toward avoiding risky bets, suggesting how past biases can influence brain activity tied to risk taking, according to the authors.
