A Window Into Your Brain: How fMRI Helps Us …

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 to the … 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 … 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 … See more The cylindrical tube of an MRI scanner houses a very powerful electro-magnet.
