Advantages of fMRI

• It can noninvasively record brain signals without risks of radiation inherent in other scanning methods, such as CT or PET scans.
• It has high spatial resolution. 2-3 mm is typical but resolution can be as good as 1mm.
• It can record signal from all regions of the brain, unlike EEG/MEG which are biased towards the cortical surface.
• fMRI is widely used and standard data-analysis approaches have been developed which allow researchers to compare results across labs.
• fMRI produces compelling images of brain 'activation' which must be interpreted carefully.
