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, … 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 … See more Oxygen is delivered to neurons by hemoglobin in capillary red blood cells. When neuronal activity increases there is an increased … See more The cylindrical tube of an MRI scanner houses a very powerful electro-magnet.
