Study reveals how the brain decides to make an effort
A new study reveals the mechanics of how the brain makes such effortful decisions, calculating whether it is worth expending effort in exchange for potential rewards.
The Proceedings of the National Academy of Sciences (PNAS) published the findings by psychologists at Emory University.
“We showed that the brain’s ventromedial prefrontal cortex, which was not previously thought to play a key role in effort-based choices, actually appears to be strongly involved in the formation of expectations underlying those choices,” says Emory psychologist Michael Treadway, senior author of the paper. He is also a NS faculty member.
Treadway’s lab focuses on understanding the molecular and circuit-level mechanisms of psychiatric symptoms related to mood, anxiety and decision-making.
