Cerebral cortical mechanisms of copying geometrical shapes: a multidimensional scaling analysis of Functional Magnetic Resonance ImagingFunctional Magnetic Resonance Imaging (fMRI)A functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.[citation needed] The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast, discovered by Seiji Ogawa. This is a type of specialized brain and body scan used to map neural activity in the brain or spinal cord of humans or other animals by imaging the change in blood flow (hemodynamic response) related to energy use by brain cells. Since the early 1990s, fMRI has come to dominate brain mapping research because it does not require people to undergo shots, surgery, or to ingest substances, or be exposed to ionising radiation, etc. patterns of activation Experimental Brain Research (2009, April) Tzagarakis C, Jerde T, Lewis S, Ugurbil K, & Georgopoulos AP Ultra-high field parallel imaging of the superior parietal lobule during mental maze solving Experimental Brain Research (2008, June) Jerde T, Lewis S, Goerke Ute, Gourtzelidis P, Tzagarakis C, Lynch J, Moeller S, Van de Moortele PF, Adriany G, Trangle J, Ugurbil K, & Georgopoulos AP Mental maze solving: directional fMRIFunctional Magnetic Resonance Imaging (fMRI)A functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow.
