Rats feel regret, it turns out!

In the study, most rats’ regret revolved around food they hadn’t eaten. I hear that, rats! I hear that. We’re not so different, you and I!

A study by scientists at the University of Minnesota recently examined the brains of rats and found they noticed when they had chosen poorly. When the rats were forced to make choices about what foods to get “in line” to consume (the most difficult kind of choices!), it wasn’t that the rats experienced simple disappointment when they lost out. They actually perceived a missed opportunity, and the areas of their brains associated with what they should have done were the ones that lit up
