Overview
This study uses a noninvasive technique called transcranial magnetic stimulation (TMS) to study hyperphagia and satiety in Prader-Willi syndrome.
TMS is a noninvasive way of stimulating the brain, using a magnetic field to change activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study, the investigators will be stimulating the brain to learn more about how TMS might improve hyperphagia in Prader-Willi syndrome.
