| Behind its protective skull, the human brain is hard to examine medically. Enter the invention of functional magnetic resonance imaging (fMRI). It’s a non-invasive imaging technique, using a powerful magnetic field and advanced computing to come up with animated 3-D images. The IU School of Medicine uses the fMRI to pick up changes in the brain when the body performs a simple motor task such as a finger tapping exercise. The finger tapping increases blood flow to the portion of the brain that governs the tapping. The fMRI is useful in diagnosis of brain cancer, stroke and Parkinson’s disease.
