Learn about required practical #7 - an investigation into the effect of a named factor on reaction times. First we cover the basics of the nervous system and all the important neurones involved. Then we look at how to carry out the experiment using caffeine as our independent variable. We then practise plenty of practical and maths techniques and problems in past paper questions to make sure you can squeeze as many marks out of your exam as possible!
