PET Scan to Study Brain Control of Human Movement
CNS Control of Human Movement: H215O PET Studies
Positron Emission Tomography (PET) is a technique used to investigate activity in areas of the brain. The PET technique allows researchers to study the normal processes in the brain (central nervous system) of normal individuals and patients with neurologic illnesses without physical / structural damage to the brain.
When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity increases, blood flow to and from the area of activity also increases. This is known as regional cerebral blood flow (rCBF). Knowing these facts, researchers can use radioactive water (H215O) and PET scans to observe what areas of the brain are receiving more blood flow.
In this study researchers plan to investigate the changes in regional cerebral blood flow (rCBF) as patients participate in different activities. The activities are designed to stimulate the areas of the brain responsible for voluntary motor activity and sensation. By comparing the results of PET scans performed in different conditions, researchers can locate regions of the brain responsible for specific tasks.
This study should provide new information about voluntary movements in humans and the preparation involved in controlling them.
