In 2003, the Nobel Prize in Physiology or Medicine wasawarded to Paul C. Lauterbur and Sir Peter Mansfield fordiscoveries related to magnetic resonance imaging (MRI).This is a tool to see the structures of the body (not just thenervous system) that depends on magnetic fields associatedwith certain atomic nuclei. The utility of this technique inthe nervous system is that fat tissue and water appear asdifferent shades between black and white. Because whitematter is fatty (from myelin) and gray matter is not, theycan be easily distinguished in MRI images. Visit the NobelPrize website (http://openstaxcollege.org/l/nobel_2) toplay an interactive game that demonstrates the use of thistechnology and compares it with other types of imagingtechnologies. Also, the results from an MRI session arecompared with images obtained from x-ray or computedtomography. How do the imaging techniques shown in thisgame indicate the separation of white and gray mattercompared with the freshly dissected tissue shown earlier?
