This second volume of Research Methods in Neurochemistry develops themes featured in the first volume and also introduces new approaches to neurochemical methodology. A further chapter on cell separation tech niques seemed justified in view of its general importance to the study of neurone-glia relationships and the complexity of the methodological prob lems involved. Biogenic amines also receive more attention in chapters on the assay of monoamine oxidase, catechol-o-methyltransferase and pineal indoles; subcellular fractionation features again in chapters on methods for the isolation and...

The fourth volume of Research Methods in Neurochemistry includes chapters on different aspects of topics touched on in previous volumes and develops a number of new themes as well. The bias, though not entirely intended, is directed toward studies of macromolecules, both at the meta bolic level in relation to protein synthesis and at the structural level in rela tion to specific proteins and lipids. The new departures concern subjects in Section I with marked applied bias: biochemical studies of nervous system tumors and of the cerebrospinal fluid, both of which we hope will be of value to...
