Book excerpt: The complement to The Rat Brain in Stereotaxic Coordinates, Chemoarchitectonic Atlas of the Rat Brain, Third Edition, features a single brain series of high-quality plates stained with eight different markers, extensively annotated and labelled throughout. Plates from the previous edition of Chemoarchitectonic Atlas of the Rat Brain have been re-scanned at high resolution and are shown in color. Labeled structures have been revised, corrected, and updated, providing users with a streamlined, up-to-date, and highly accurate compendium of chemical markers. Researchers with a need to understand the detailed organization of the rat brain as well as structure/function relationships will need this atlas and its array of stains. - Provides an archive of chemical markers in the rat brain used in many areas of research - Discusses primary data to help researchers identify structures in their own preparations from neuroanatomical, physiological, neuropharmacological, and gene expression studies - Accompanies the gold standard reference on the neuroanatomy of the nervous system of the most important model animal in neuroscience and experimental psychology - Covers both the rat forebrain and the rat brainstem - Thoroughly revised identification of structures following the new data from The Rat Brain in Stereotaxic Coordinates 7th edition and the Chick Brain in Stereotaxic Coordinates 2nd edition - Includes the Expert Consult eBook version, compatible with PC, Mac, and most mobile devices and eReaders, which allows readers to browse, search, and interact with content
