Fmri magnetic electric induction
Functional magnetic resonance imaging or functional MRI (fMRI) 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. The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contr… WebSep 19, 2024 · Electromagnetic induction is the induction of electric current via changing magnetic fields.

WebMagnetic resonance imaging (MRI) is a noninvasive test doctors use to diagnose medical conditions. MRI uses a powerful magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of internal body structures. MRI does not use radiation (x-rays). Detailed MR images allow doctors to examine the body and detect disease.
