Fmri injection
The fMRI concept builds on the earlier MRI scanning technology and the discovery of properties of oxygen-rich blood. MRI brain scans use a strong, permanent, static magnetic field to align nuclei in the brain region being studied. Another magnetic field, the gradient field, is then applied to spatially locate different nuclei. Finally, a radiofrequency (RF) pulse is played to kick the nucl… WebA previous study of electrophysiology and functional MRI has suggested that a 0.5 g/kg fluorodeoxyglucose injection can be tolerated with minimal effects on baseline cerebral physiology and on brain function during neural stimulation 34. Our electrophysiology measurements with a dose of 0.6 g/kg indicates that xylose has a much milder effect ...
