Because the brain is so complex, researchers are forced to devise all manner of different types of tests in trying to understand not just how it works, but which parts of it do what. To that end, a diverse group of scientists from several universities across the U.S. got together to work on the problem of which parts of the brain, if any specifically, are involved in analyzing and making moral judgments. To find out, or at least learn more, they devised three experiments meant to test the busyness of the brain, measured by blood flow, to certain regions, when presented with immoral situations. They have published the results of what they found in the journal Frontiers in Evolutionary Neuroscience.
