Q: Will questions on techniques, results, and background be included?
A: Yes, questions on the exam may cover all these topics.
A: You are expected to have a good understanding of the questions being addressed in your proposal, the experimental approaches used to address the questions, the conclusions drawn from the experiments, and their significance to the field. Questions may be asked that require you to interpret detailed data. We are not trying to test if you can memorize details but rather that you have gained a good grasp of the important concepts in a range of study topics.
A: It is your obligation to clarify your understanding of areas covered in your proposal. While you should use this as an opportunity to familiarize yourself with new subjects, it is also important that you don’t focus on trying to memorize, but rather take some time to think about what they mean. You should consider the big picture. What is interesting about these areas? Where is the field headed next? What would be the significance of the findings to biomedicine? If you approach it in this way, you will understand the topic better and you will be ready to answer.
A: You are scholars studying for an advanced degree. Your job is to convince the grader that you understand the topic being discussed. The exam is intended to demonstrate that you can educate yourself about recent advances in science. Understanding is not the same as simply memorizing. If you understand the topic you will be able to explain your answer with a clear rationale.
A: The faculty are ultimately responsible for certifying that a student has achieved a doctorate degree in Neuroscience. This exam allows the faculty to determine whether graduate students have the motivation and intellectual ability to be considered as a potential candidate for this academic degree. ?
A: Once you are awarded a Ph. D. degree, tests don't stop. They only continue to get more competitive. These tests come in the form of doing high quality research, submitting original papers to refereed journals, applying for fellowships and research grants, applying for a permanent position in industry, research and/or teaching, and undergoing professional scrutiny by a university tenure or promotions committee. Your success in these endeavors requires many other skills besides knowing a textbook from cover to cover. This exam provides a taste of practical scientific life and will help you to prepare for competition in the real world. ?
A: Scientific work progresses in many different ways. Much science simply involves the collection of facts. Genome sequencing is a fact gathering activity that will lead to many new breakthroughs. These breakthroughs will come by analysis of such information and the formulation of new hypotheses. It is essential for graduate students to learn how to do hypothesis-driven research. Thus, in this exam it is not appropriate to simply propose to purify a protein or clone a gene. In this exam, you should study existing scientific data and synthesize it to propose an original mechanism for some well-defined phenomenon. This is quite an opportunity. Often, a naive mind is able to see things in a fresh way that old bosses cannot envision. Your hypothesis may actually be the key to solving an important problem. Do not simply try to demonstrate something trivial. Ask a hard question and try to devise a route that will yield the answer. ??
A: The dictionary says that a hypothesis is merely a proposition to explain certain facts. A good hypothesis provides a rational explanation for a curious phenomenon of nature or a fundamental aspect of living systems. The key feature of a good hypothesis is that is makes definite mechanistic predictions that can be tested. It answers the simple question: How does it work? Some examples of great, Nobel Prize winning hypotheses are:
- Genetic Information is encoded by DNA (Crick, Watson & Wilkins, 1962) ?
- RNA can act as a catalyst (Altman & Cech, 1989)
- Viruses that cause cancer can do so with genes pilfered from normal cells (Bishop & Varmus, 1989).?
- GTP-binding proteins couple hormone receptors to cAMP production (Gilman & Rodbell, 1994)
- Endothelial cells release a gas that can relax blood vessels (Furchgott, Ignarro, & Murad, 1998)
A: The interpretation of every experiment is subject to the influence of confounding variables. A good experiment must be designed to isolate only the variable that is to be tested. For example, if you propose to test whether the introduction of a certain gene into a cell by viral transfection affects a particular cellular process, how do you know whether the virus itself modifies this process independently of the candidate gene? Clearly, one must include a control virus lacking the tested gene in this experiment. The elegance of experiments critically depends upon the identification and inclusion of the most appropriate controls that rule out artifacts and misinterpretation of the results. ??
A: The best way to avoid nervousness is to put forth your best effort in designing a brilliant research proposal. Research your ideas thoroughly and master the basic knowledge related to your topic. Organize practice sessions with fellow students (especially those who have previously passed the exam) and ask them to critique your presentation. By the day of the exam, you will be able to articulate your ideas, and have confidence in your ability to defend them in front of the faculty. ?
A: A majority of students are able to pass this exam. Sometimes a committee is dissatisfied with a performance and will not issue a passing grade. If the committee believes that the student is capable of improvement with hard work, the student may be offered a conditional pass. Rarely, a student may fail the exam even after a second attempt. This is a serious decision by the faculty that the student does not have the capability to perform research at the doctoral level. If this happens, the important thing to remember is there are many other excellent options for your career. Failing the qualifying exam may actually be a relief to some students, because it signals that an alternative to a research career is an advisable option. Students who do not pass the exam may write a masters thesis and be awarded a Masters degree. They are qualified for many exciting opportunities in the private sector that make use of their scientific background and training. Some may choose to pursue additional education in business or health-related fields. Many faculty members are able and willing to advise students on these options. The idea of failing such an important exam may seem devastating, but all of us must eventually learn to cope with failure.
A: The proposal should be conceived and written entirely by you. No one is allowed to "coach" you on the topic or the experiments you choose to propose. However you are strongly encouraged to show a near-final draft to any non-faculty member who is willing to read it, for advice on how to effectively communicate and defend YOUR ideas. You are also strongly encouraged to read other successful grant proposals that are stored in the Neuroscience Program Office. Clear logical writing is one essential element of a successful grant, and this exercise should be a learning experience in that regard. ??
A: It is a time to celebrate your accomplishments with your friends, relatives and colleagues. You have demonstrated potential ability in your chosen field and have been selected to perform original thesis research that will be completed over the next few years.
