Some prefer to work at the molecular level, unravelling the contribution of variations in gene expression or intra- cellular proteins to normal function or neuropathologies. Others are engaged in understanding the electrical properties of neurons or the chemistry of the brain and still others prefer to study the overt behavior of an organism and surmise about the design of the 'black box' which produces such behavior. Not surprisingly, a large number of very specialized techniques have been developed to allow these avenues of study. Most undergraduate, honours and new PhD students find the plethora of techniques bewildering. As a consequence they have trouble understand- ing original papers and find it difficult to critically appraise them. To help solve this problem, I asked a number of colleagues to each write a few pages about a method they used to study the nervous system. I particularly requested that they directed their writing towards an outline of the methodological principles and potential pitfalls of the technique they chose to describe. It is always difficult to know where to stop with a book such as this. In the main, the techniques described are those used in animal experiments but I have chosen to include a few chapters on electrophysiological measurements in humans. Descriptions of some modern imaging techniques such as NMR, PET and SPECT and behavioral methods will have to wait, perhaps for another edition. This book is the outcome of the labors of my many colleagues and I thank them all for so generously giving their time. I also wish to thank Garry Rhoda for his excellent editing of diagrams and Audra Johnstone for preparing the manuscript in its final form. IX
