fMRI or functional magnetic resonance imaging was one of the great inventions of the 20th century. It revolutionised medical fields allowing for examination of the body without the need to cut someone open. Equally neuroscience moved from a field constrained either to understanding the brain through surgery (hardly the same as in day to day life) or with EEG which only measured coarse electrical signals. With fMRI second by second imaging from inside the brain of a living, responding person was in grasp and after decades it is now a common place technique in dozens and dozens of neuroimaging labs across the world.
But how does it work? Could you even hazard a guess? This episode brings in neuroimaging lecturer and expert on EEG and fMRI Dr Stephen Mayhew to provide a tutorial on fMRI. We go through it step by step from the atoms that have to be aligned and provoked to even get the signal all the way to a laymen’s explanation of how a brain image is generated for displaying on the evening news. While WCNeuro can’t promise you’ll be a qualified operator by the end you will know the ins and outs of one of the marvels of the modern age.
