A published scientific paper is essentially a lab report like the one you’re writing. The goal of a scientific study is to test one or more hypotheses. In Neuroscience, these hypotheses represent interpretations of how the brain or some portion of the nervous system functions. One goal of this course is to begin training you in how to go about testing a hypothesis and to think about the results that you obtain. A scientific paper discusses results in terms of whether they prove or disprove the hypothesis. As you write your lab report, think about it as if your experiments tested new hypotheses . Clearly, the principles being tested in these two labs are already well established. Any good scientific observation, however, should be able to be replicated when tested correctly. We’re asking you to prove these established principles anew. Introduction These two labs demonstrate some important principles in Neuroscience. You should treat these principles as three hypotheses that your experiments tested. First , propose that nerve conduction is independent of stimulus intensity. Second , hypothesize that there is a delay between the action potential reaching the neuromuscular junction and the muscle generating an action potential, the synaptic delay. Third , propose that muscle force is a function of the number of active motor units and frequency of motoneuron discharge. Organize your Introduction around these three hypotheses. For each hypothesis: A) provide background evidence from animal studies supporting the hypothesis; B) explain how the hypothesis can be tested in an awake human; and C) supply references to support your statements. Materials and Methods In this section, succinctly describe the procedures you used for your experiments. Everyone has a copy of the lab manual, so just hit the highlights. Be certain to tell the reader about any changes from the lab manual that you made in your procedures. Experimental Results To understand the data that you obtained in Labs 6 & 7, you need to organize it so that you turn your collection of observations into answers to specific questions. Creating graphs of your numerical data is a valuable way to visualize your data. Sometimes a graph will provide information that you will want to share with the reader in order to support or disprove your hypotheses. Informative figures enable you to describe your data effectively to the reader. Some graphs, however, may not demonstrate anything useful and do not need to be shared. (‘Brevity is the soul of wit’)
