Scientists have figured out how to stop monkeys from taking risks

A team of researchers from Kyoto University in Japan used flashes of light from implanted chips to trigger two separate sections in the brains of macaque monkeys.

Switching on one encouraged the primates to take bigger risks in the hope of a bigger payoff, while switching to the other caused the monkeys to settle for a smaller but safer reward.

The experts behind the study say the experiment offers insights into the neural roots of gambling addiction.

In an accompanying commentary, Veit Stuphorn – an associate professor of neuroscience at Johns Hopkins University who was not involved in the work, said: “This unexpected finding implies that two neighboring regions in the frontal cortex jointly regulate risk attitude in a competitive push-pull. “-like fashion and can both increase and decrease risk-taking.

“This is important because it opens the possibility of identifying the neural mechanisms in the circuit that underlie this ability.”
