Functional MRI imaging in localizing motor paradigm

Abstract

Objectives – Understanding how brain works was the neuroscience’s goal, since day one. The cerebral analysis development’s came along with the widespread of fMRI usage. Following the neuroscience facts, this study aims to identify the cerebral localization of the motor cortex, in a young and healthy population. By allowing a better knowledge of this area, it gives an important contribution to the neurology science. Material and methods – fMRIs were performed in 30 healthy subjects, in clinical medical imaging. To achieve this purpose, we employed proper resonance equipment. The motor paradigm used was the fingers’ movement. By the obtained images, the region’s areas were measured. The data were analysed by a statistic program (SPSS version 19). Conclusion – In conclusion, we observed that the area which was more active, when motor paradigms were in execution, relies on left cerebral hemisphere.
