This course has been designed as a seminar to give students an understanding of how scientists with medical or scientific degrees conduct research in both hospital and academic settings. There will be interactive discussions with research clinicians and scientists about the career opportunities and research challenges in the biomedical field, which an MIT student might prepare for by obtaining an MD, PhD, or combined degrees. The seminar will be held in a case presentation format, with topics chosen from the radiological sciences, including current research in magnetic resonance imaging, positron emission tomography and other nuclear imaging techniques, and advances in radiation therapy. With the lectures as background, we will also examine alternative and related options such as biomedical engineering, medical physics, and medical engineering. We'll use as examples and points of comparisons the curriculum paths available through MIT's Department of Nuclear Science and Engineering. In past years we have given very modest assignments such as readings in advance of or after a seminar, and a short term project.

In this case, students assume the role of a fictitious space explorer captured by aliens. To win their release, they must correctly explain the neurophysiology underlying some of the punishments used by the aliens to deter attempts at escape. The purpose of the case is two-fold. First, it strengthens students' understanding of ion channel function to the point where they are able to make predictions about the ability of the cell to generate an action potential if the activity of a particular ion channel is altered. Second, students are encouraged to place neuronal signaling in a larger context by hypothesizing how altered activity in a specified region or division of the nervous system will be manifested in physical symptoms. While written for a two-semester anatomy and physiology course, this case would also be useful in an undergraduate physiology or neuroscience course or in any course in which students must gain an understanding of foundational neurophysiology.
