The purpose of this research study is to study the capabilities of new methods for studying the brain using Magnetic Resonance Imaging (MRI). MRI already provides detailed images of brain anatomy, but newer methods including new MRI techniques and magnetic resonance spectroscopy expand this capability. These new MRI methods will not require any invasive procedures. If successful, these new methods will expand the information, which can be obtained from MRI studies of the brain in patients with epilepsy.
