No pain, no gain? How the brain chooses between pain and profit

No pain, no gain? How the brain chooses between pain and profit Imagine having to choose over and over between what you enjoy doing and the pain that it might cause you, whether physical or emotional. If you live with conditions such as depression, anxiety, or chronic pain, you are probably familiar with making these difficult choices on a daily or weekly basis. But surprisingly little is known about which areas of the brain are involved in decisions of this kind. In a recent article in PNAS , McGill researchers show that the ventral striatum plays a crucial role when it comes to choices about future pain versus future profit. Interestingly, this brain region has already been identified as being involved in motivation and rewards, but it has not been associated with pain until now. This discovery could advance treatments for a range of disorders that are characterized by excessive avoidance. To see which areas of the brain were activated during decisions about future pain and profit, participants in the recent study were asked to make choices, very quickly, that involved a certain (random) amount of pain in exchange for a certain (random) amount of profit - or vice versa.
