Physics And Physiology

MRI operates by creating and detecting a signal generated by the physical phenomenon of NMR. Although an in-depth explanation of the physics of NMR and the technology of MRI is beyond the scope of this article, a basic understanding of how a MR scanner operates is useful in discussing fMRI in its applications to psychology and medicine. The following discussion is based on a description of the "classical electrodynamics" picture of NMR and MRI. A more rigorous and complete treatment of NMR would require quantum mechanics, but MRI is best understood in terms of classical electrodynamics.
