Functional magnetic resonance imaging (fMRI) measures changes in blood flow related to neural activity in the brain using magnetic fields. fMRI has relatively high spatial resolution and therefore researchers can obtain accurate information on the location of changes in the brain. fMRI also allows for the retrieval of information from deeper brain structures. However, because reaction in the brain is not immediate, fMRI provides relatively low temporal resolution.
The Edmond J. Safra Center conducts fMRI studies at Sheba Medical Center and at the Rambam Healthcare Campus. In an fMRI experiment, subjects must lie still in order to obtain the necessary measurements, while being presented with audio or visual stimuli. fMRI measurements are used in studies on reading and reading-related skills.
