Did you know?
WebFunctional magnetic resonance imaging, or fMRI, might be the most widely known technology for recording neural activity, but it doesn’t actually record activity of neurons – instead, the multicolour images you see of particular brain regions being lit up reflect blood flow in the brain. http://mriquestions.com/bold-contrast.html
