Lipids m the nervous system are major components of the m- branes. The presence of glycolipids in high concentrations is unique for the nervous system. Recent discoverres of the functronal and pathological importance of lipids such as diacylglycerols, polyphosphoinositides, prostaglandins, leukotrienes, docosahexaenoic acid, platelet activating factor, and gangliosides have markedly increased the number of publications on nervous system lipids. Many new methods have been developed. Thus, there IS a need for this volume that is dedicated to that methodo- gy. This volume places all of the methods for lipids into perspective with recommendations concerning the selection of a method for a specific purpose. Lloyd A.
