Functional Magnetic Resonance Imaging of Cerebral Cortex Related to Movement

Objectiive:To investigate the functional activation areas in cerebral cortex related to movement,and assess whether preparation- and execution-related activity could be observed within individual motor areas.Methods:During event-related fMRI,fourteen right-handed healthy subjects performed a sequential movement task,to get the functional activation maps of related cerebral cortex during the preparation and execution periods of finger movement.Results:Bilateral pre- supplementary motor area (pre-SMA),posterior premotor cortex (PMC) and anterior postrior parietal cortex (PPC) were activated during both the preparation period and the execution period.Conclusion:These findings suggest that preparation- and execution-related activity could be observed within individual motor areas,the event-related fMRI technique is a feasible method in the study of the brain activity.
