In this video segment adapted from Curious, researchers at Caltech determine how the brain responds to making positive and negative moral decisions by setting up a give/take experiment. Subjects are challenged to either give meal donations to orphans who live in a children's home in Uganda, or to take meals away. Researchers chronicled the positive feelings that resulted during the "give" scenario, when the part of the brain called the orbital frontal cortex was stimulated, and the negative feelings that resulted in the "take meals" scenario, when the insula part of the brain was stimulated.
