Understanding brain function and localizing functional areas has been the goal in neuroscience and functional magnetic resonance (fMRI) is a very powerful tool to approach this aim. fMRI is a magnetic resonance imaging technique to measure brain activity via changes in the local oxygenation of blood, which in turn reflects the amount of local brain activity.
fMRI allows us to measure all aspects of the mental processes involved in awareness, reasoning, and acquisition of knowledge and behavior in the field of Cognitive Neuroscience while use of FMRI in the Medical Sciences focuses on localization of brain regions for a large variety of clinical applications.
fMRI is currently one of the most exciting and progressive times of scientific advancement in the field of brain studies. It is non-invasive and safety technique to measure excellent spatial and temporal resolution.
