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) … 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. When neuronal activity increases there is an increased demand for oxygen and the local response is an increase in blood flow to regions of … See more The cylindrical tube of an MRI scanner houses a very powerful electro-magnet.
