introduction should contain only the relevant information about the experiment, and a little background. don’t add a lot of irrelevant details because that might take away some marks. include the aims of the experiment (very important).in the methods section always write in past tense, talk about the preparation of the sciatic nerve tissue. info about general way that CAP are measured (don’t write details about each one of them bc that will be in the results section).in the discussion don’t describe the data, just an interpretation about the results and methods and how they meet the aims in physiological terms, and also use methanistic reasoning.
