Functional magnetic resonance imaging, or fMRI, is a technique for measuring brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases … See more The development of FMRI in the 1990s, generally credited to Seiji Ogawa and Ken Kwong, is the latest in long line of innovations, including positron emission tomography (PET) and near infrared spectroscopy (NIRS), … See more The attractions of FMRI have made it a popular tool for imaging normal brain function especially for psychologists. Over the last decade it has provided new insight to the investigation of how memories are formed, language, … See more Oxygen is delivered to neurons by hemoglobin in capillary red blood cells.

Physicians use fMRI to assess how risky brain surgery or similar invasive treatment is for a patient and to learn how a normal, diseased or injured brain is functioning. They map the brain with fMRI to identify regions linked to critical functions such as speaking, moving, sensing, or planning. This is useful to plan for surgery and radiation therapy of the brain. Clinical use of fMRI still lags behind research use. Patients with brain pathologies are more diffi… WebFunctional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity.
