Brief Summary:
This study will evaluate new magnetic resonance imaging MRI methods using a MRI machine more powerful than those in most hospitals MRI is a diagnostic tool that uses a large magnet and radio waves to produce images of the human body It can also provide information about brain chemistry and physiology This study will use the new MRI hardware and methods to measure blood flow and metabolism in regions of the brain during simple tasks such as listening to tones or watching flashing checkerboards
Healthy normal volunteers will undergo MRI scanning For this procedure the person lies on a stretcher that is moved into a MRI machine which produces a strong magnetic field A special lightweight coil is placed on the persons head to obtain better pictures The scan time ranges from 20 minutes to 2 hours with the average scan lasting between 45 and 90 minutes
During the MRI the person may be asked to perform simple tasks such as listening to tones or watching a screen tapping fingers or moving a hand More complex tasks may require thinking about tones or pictures and responding to them by pressing buttons
The images produced in this study will be compared with those produced using standard MRI The results will be used to develop improved imaging methods for better patient care and research

Detailed Description:
Technical advances in Magnetic Resonance Imaging MRI and Magnetic Resonance Spectroscopy MRS has provided researchers with the opportunity to study functional and metabolic changes of the central nervous system CNS in both healthy controls and individuals with neurological diseases in response to sensory motor or cognitive stimulation While MRI is in common usage in radiology departments and clinics MRI and MRS techniques and hardware are continually being upgraded and designed for Functional Magnetic Resonance Imaging fMRI and Magnetic Resonance Spectroscopic Imaging of the CNS at 30 Tesla We will evaluate new sequences on volunteers and for potential use in patients with CNS pathology These studies are required in order to develop and implement new imaging techniques for research and clinical applications
