<qa>  What is a brain scan called?Background- This is a study of the way people with schizophrenia may feel when they get rewards. Certain parts of the brain play a part in people feeling happy when they win some sort of reward or have a good thing happen to them. Some people with schizophrenia may have trouble feeling pleasure because part of their brains, the frontal cortex, may not work properly. We are doing this study to understand how the frontal cortex works in people with and without schizophrenia when they are trying to win a reward. We will use a special kind of brain scan called Functional Magnetic Resonance Imaging fMRI to show the brain working in action. fMRI scanning uses a big magnet to take special pictures of the brain.
