Abstract
In recent years the fields of medicine and physiological research have made many advancements as a result of application of technology. One example of this is the device known as the Magnetic Resonance Imaging machine (MRI). MRI machines use innovative methods based on principles of physics and electronics to effectively attain a cross-sectional view of the human body. The MRI machine emits an electromagnetic field in the presence of a static field to manipulate the nuclear spin of hydrogen atoms in the body. The received signal can then be interpreted and reconstructed to plot a picture of the section examined. This is all done quickly and without the negative side effects of radioactive materials or surgery. A particular application of MRI machines is referred to as functional MRI (fMRI). Functional MRI specifically monitors brain activity by using the contrast difference resulting from increased oxygenated blood flow to active areas of the brain.
