Functional Magnetic Resonance Imaging (FPN)

The MRI (magnetic resonance imaging) scanner is used to study brain functions. Researchers use the MRI scanner to examine the active brain areas of test participants, usually while they perform a certain task. These brain areas use more oxygen than when at rest; this causes small changes in the local magnetic field that can be observed using the strong magnetic field produced by the magnet. This allows researchers to study how the brain functions for instance, how it processes images of food as compared to images of neutral items under various conditions (e.g., hunger vs. satiety or attended vs. unattended), and how this differs between healthy weight and overweight people.
